Introduction The system uses the mains cables to communicate between the Controller and all the heaters. Do not spur the Controller electrical supply from the dwellings light circuit. (In some situations the house lighting can effect the mains borne signalling used by Credanet II) Do not install the Controller where there is an RCD device in between the Controller supply and the Maintained supply to the heaters. (RCDs can effect the mains borne signalling) The heating scheme for the house must be detailed in the planning sheet on Page 5 prior to setting up the Controller and Heaters. The number of zones that are used and the heaters in each zone is set into the Controller and Heaters during the Programming process (See Section 3 Page 6) Page 2

3 a) Zone : The Controller allows for a heating scheme to be divided into three separately controlled zones. ZONE 2 ZONE 3 A zone is a group of one or more rooms with one or more heaters. A Credanet II installation can have up to three zones. ZONE 1 b) Heater Number : Each zone can contain up to 15 heaters. (Numbered 1 to 9 then A to F). The heaters in each zone will follow the temperature program set at the Credanet II Controller. ZONE 2 ZONE ZONE c) House Address : This is a unique five figure number that is randomly created by the Controller when it is first powered up. (The house address can be changed to a specific value if required). This number is set into all the heaters in the house during the Programming process (See Section 3 Page 6) Example House Address d) Heater Type : The Credanet II system can be used with the following Credanet II heaters Panel Heaters Combi Storage Heaters Storage Fan Heaters (Direct Energy only). (Stored and Direct Energy) (Stored Energy extracted as needed by fan) Page 3

4 2. Filling out the Planning Sheet (See Page 5). Before the Controller and Heaters can be programmed, the Planning sheet on Page 5 must be completed. To do this, decide how the heaters want to be specified in the controller and then write this onto the Planning sheet. This information is then programmed into the controller. a) Key The controller needs to know the Code for each heater in the house, according to the table below. (This goes in the column labelled Type ). Heater Type Panel heater Auto Combi Storage Fan Part Number CNTxxP CNTxxC CNTxxF Controller Code PA AC C SF Notes Fan can be switched on by the controller and heater Boost button Fan can only be switched on using the heater Boost button Bedrooms : To prevent the fan possibly activating during the night use Code C rather than AC Note: The controller has an additional code PC : Please do not use this code (It is for future use). Each heater must be allocated a Zone and Heater number. (This goes in the column labelled Ref ). (For example 3:4 is Zone 3, Heater N 4). b) Example: An example scheme is shown below. In this example the house has a Storage fan in the lounge, an Auto combi in the dining room, an Auto combi in the kitchen and panel heaters in three bedrooms. Zone 1 Zone 2 Zone 3 Location Type Ref Location Type Ref Location Type Ref Heater 1 Lounge SF 1: 1 Dining Room AC 2: 1 Bedroom A PA 3: 1 Heater Kitchen AC 2: 2 Bedroom B PA 3: 2 Heater Bedroom C PA 3: 3 NOTE : When the Table on Page 5 is completed : For the benefit of the customer. Complete the Room Allocation Chart in the Customer Handbook Credanet II - User's Guide. Page 4

6 3. Programming the Controller and Heaters In this section the information on the Planning sheet is programmed into the Controller and Heaters. a) Before starting this section make sure: All the heaters are installed and wired to the electrical supply. (If a heater PCB has already been programmed it may need to be reset: See Section 8 Page 16) Note : For a Storage heater (Type SF or AC or C) to work correctly the off peak and maintained supplies MUST be connected to their correct terminal blocks AND left switched on at all times. The controller has not been previously programmed. (A controller that has already been programmed may need to be reset: See Section 7 Page 14) An un-programmed Controller will only show the time and day when powered up. A Controller that has already been programmed will also display up to three temperatures. The battery switch on the reverse of the Controller must be set to ON. The power MUST BE OFF to all heaters except Heater 1 in Zone 1. The Planning sheet on Page 5 is completed. Notes : During the initial power up a controller will display the following information : 1) A blank house address is shown as A new random address is created by the controller 2) The three zones are shown with no heaters programmed. The controller will show 0: 0: 0: 3) The controller then carries out a check on any heaters that have already been set into the controller. (No check is made on a controller that is blank 0: 0: 0: ). If the Controller is not empty as shown in 2) above it can be reset as detailed in Section 7 Page 14. If the screen remains blank at power up then it can be reset. (See How to Reset the screen Page 15). Page 6

7 b) Set the Controller to Install Mode : The programming is done with the Controller in Install Mode To put the controller into Install mode Then press the following button sequence : Move slider switch to Holiday position Button D then H then G then E then H. The controller is in Install mode when the 00 on the display changes to In. Slider in Holiday Setting c) Program the details of Zone 1, Heater 1 into the controller Install Mode On the controller: 1) Enter the install mode and move the selector to Prog. Run position. 2) The house address stored in the controller will be displayed. (This address is randomly generated by the Controller. If a different value is required then change it NOW by using the three sets of + and buttons to change to a new value) IMPORTANT Any changes to the House address MUST be done NOW, before starting the next section. (Once the Boost button is pressed on the first heater, the House address MUST NOT be changed) 3) Move the slider to Zone 1 4) Now go to Zone 1, Heater 1 and press the Boost button on the heater for 2 seconds. (Important : Make sure the electrical supply is OFF to ALL the other heaters in the house). The display will look like this Page 7 The display will now look like this

8 d) Changing the screen details The Controller screen needs to be set to the details in the Planning sheet for Zone 1, Heater 1. With the Selector switch at Zone 1 the three sets of + and buttons are used to alter the heater Type, the Zone number and the Heater number. (In the Planning sheet the Zone and Heater number Ref is shown in the style 1: 1 ). Note : The Middle Select button is used for Controller diagnostics. If it is inadvertently pressed then press it twice more to return to the Programming screen. Use the left hand pair of + and buttons to : Change the Heater Type to the one specified for Zone 1, Heater 1. (E.g. SF). When the screen details are correct : Press the left hand Select button to send the information to Zone 1, Heater 1. (The Heater details are successfully Sent to the Heater when the OFF changes to ON ). e) Program the details of the rest of the heaters into the controller Leave the Controller in Install Mode and, if necessary, move the slider to the required zone number. Go to the next heater in the house and turn on its power supply. (The power can be left on to the heaters that have already been programmed but MUST remain OFF to any heaters waiting to be programmed). Press the Boost button on the heater for 2 seconds. Return to the Controller where the next heater will have registered on the screen. (See below) Page 8

9 The new heater will register as the next available Zone and Number and display SET on the screen. If the heater zone and number is not correct according to the Planning sheet then : 1) Un-SET by pressing the right hand Select button and then 2) Use the middle and right hand sets of + and buttons to change to the required Zone and Heater number. Use the left hand + and buttons to change the Heater Type to the one specified in the Planning sheet. (E.g. AC). When the screen details are correct : Press the left hand Select button to send the information back to the heater. (The Heater details are successfully Sent to the Heater when the OFF changes to ON ). Note : Be sure to Un-SET the heater from the screen if it is in the wrong location. Each heater in the house is programmed in the same way. Make sure that any zone and number locations that are NOT required are Un-SET from the screen. Only press the left hand Select button when you are ready to confirm the settings back to the heater. f) Locking the User Heating Plan In some situations it may be required to prevent the User from being able to change the Heating Plan set for the property. (The Heating Plan is described in the handbook ~ Credanet II User s Guide). A separate leaflet is available from Creda Heating describing how to prevent the user from making adjustment to the heating plan. (Credanet II How to lock the User Heating plan). 4. Take the Controller out of Install Mode When all the heaters have been programmed, the controller needs to be returned to normal. To do this : Move the slider to the HOLIDAY position (The controller in Install mode will look like this) Press ANY button except the middle + Slider at Holiday and Controller in Install Slider at Holiday and Controller in normal Mode Move the slider switch to Prog. Run position. To alter the clock and to change the Zone temperatures and timings see separate handbook - Credanet II User s Guide. Page 9

10 5. Checking the system setup a) Checking the Planning sheet settings are correct on the Controller The program setting on the controller and all the heaters in the system can be checked as follows : Use the completed Planning sheet on Page 5 to verify that the controller and heaters are set correctly. Put the Controller into Install Mode (See Page 7) and then the move slider to Zone 3. Go to Zone 1, Heater 1 and press the Boost button for 2 seconds. The Controller will display the settings for that heater on the screen. For Example : (Changes can still be made at this stage : To do this, Un-SET the heater from the screen, make the necessary changes and then re-set by pressing the left hand Select button See Section 3 for details). All the heaters in the system can be checked in the same way (By pressing the Boost button and checking the details on the screen of the Controller). When the checks are completed, take the Controller out of Install Mode. (See Section 4 Page 9) b) Checking House address and communication between Controller and heaters On a completed system the house address, and successful communication to the heaters, can be checked. Make sure that the setting up and programming of the system is complete (See section 3 Page 6) and that the power is on to all the heaters. Turn the power supply to the controller off and on again. During the power up the display on the controller will show the following information. Page 10

11 The house address is shown. (A new random address is created if the display is ). For example : This controller already has its house address set to The number of heaters allocated in each zone is then displayed. For example : This Controller has already been set with 3 heaters in Zone 1 (shown as 3:) 5 heaters in Zone 2 (shown as 5:) 4 heaters in Zone 3 (shown as 4:) The Controller then carries out a communication check with each heater in sequence. In this example : Zone 1 has been checked (and shows 18) Zone 2 heater 1 is being checked (shown as 5:1) (5 heaters in total) and Zone 3 has yet to be checked (and shows 16) For the check to be successful : The heaters must be powered up and Already programmed to the controller An individual heater communication check is successful if it takes less than 10s to complete. 6. Adding or replacing a heater. Replacing a Controller a) Adding a new heater : When the new heater has been added. Add the new details of Zone, heater Number and Type to the Planning sheet on Page 5. Put the Controller into Install Mode (See Page 7) and move the slider to the Zone containing the new heater. Switch on the power to the new heater and press the Boost button for 2 seconds. The controller will show the next available heater for that zone. Check that this number is correct according to the planning sheet. (If the number is not correct then use the right hand Select button to Un-SET it, change the screen to the correct number, and Re-SET) Use the left hand + and buttons to specify the correct heater Type. When the details on the screen are correct : Press the left hand Select button to send this information back to the new heater. (See Section 3 Page 6 for details on how to program the Controller and heaters). Page 11

12 b) Replacing a heater in a Credanet II system: When the old heater has been replaced. Put the Controller into Install Mode (See Page 7) and move the slider to the Zone containing the replacement heater. Switch on the power to the new heater and press the Boost button for 2 seconds. The controller will show the next available heater for that zone. If necessary, un-set this heater position from the Controller screen using the right hand Select button. Use the right hand + and buttons to locate the correct heater number of the replacement heater, according to the details on the Planning sheet on Page 5. When the details on the screen are correct : Press the left hand Select button to send this information back to the new heater. (See Section 3 Page 6 for details on how to program the Controller and heaters). c) Replacing a heater in a Credanet I system: Heaters in a Credanet I system can be replaced with a new Credanet II type. (Credanet I uses DIP switches to commission the heating scheme) Notes : A Credanet II heater can only be programmed using a Credanet II Controller. After the new heater has been programmed, the existing Credanet I controller can be reinstalled. IMPORTANT Make a note of the Zone and Heater number of the Mk I heater being replaced. When the old heater has been replaced. Ensure the power supply is On to all the Mk I heaters and Off to the new Mk II heater. Temporarily replace the existing Credanet I controller with a Credanet II controller. On the controller: Enter the Install Mode (See Page 7) and move the selector to Prog. Run position. The house address stored in the controller will be displayed. This address is randomly generated by the Controller, e.g The House address (HA) on the Mk II controller MUST be changed so that it is the same as the one used by the existing Mk I heaters. The HA on the Mk II Controller is changed as follows: Press the left hand Select button to remove the house address from the screen. (Shown as ) (The random house address, e.g , is still retained by the Controller, but the value is removed from the screen) Page 12

13 Now go to one of the existing Mk I heaters. Make sure the power is on and press its Boost button for 2 seconds. The heaters house address will now appear on the screen of the controller. (e.g ). (The new controller has been forced to take the house address that already exists on the Mk I heater) Move the slider to the Zone containing the new heater Turn on the power to the new heater and press its boost button for 2 seconds Note : The randomly generated house address has been over-written by the address already stored in the heater. At the controller use the + and - buttons to change the screen details so that the Zone number, Heater number and Heater type is correct. (This MUST be the same as the old heater being replaced) When the screen details are correct, press the left hand Select button to send the information to the new heater. On completion, replace the temporary Credanet II controller with the existing Credanet I. If the Credanet II controller is being kept then it will need to be programmed with all the heater details. See section d) below. See Section 3. Page 6 for details of how to program Credanet II heaters. d) Replacing a Controller : A new Controller can be installed into an existing system and programmed with the information already set in the heaters. This method will also work when replacing an existing Mk I controller. When the new controller has been added. Power up the new Controller and all the heaters in the system. On the controller: Enter the Install Mode (See Page 7) and move the selector to Prog. Run position. The house address stored in the controller will be displayed. This address is randomly generated by the Controller, e.g For the new Controller to work correctly this address MUST be changed to the existing address stored on the heaters as follows : Press the left hand Select button to remove the house address from the screen. (Shown as ) (The random house address, e.g , is still retained by the Controller, but the value is removed from the screen) Page 13

14 Now go to one of the heaters. Make sure the power is on and press its Boost button for 2 seconds. The heaters house address will now appear on the screen of the controller. (e.g ). (The new controller has been forced to take the house address that already exists on the heater) Pressing the Boost button will also register that heaters details (Type/Zone/Number) onto the new controller. Note : The randomly generated house address has been over-written by the address already stored in the heater. Go to all the other heaters in the house and press their boost button. (This will register their heater details onto the new controller). The new Controller is commissioned when all the boost buttons have been pressed. Check that the new controller has registered all the heaters. (See Section 5 Page 10). Return the Controller to normal. (See Section 4 Page 9). 7. How to reset a Controller This process is in two parts. The first part removes all the allocated heaters from a Controller and leaves the house address unchanged. The second part removes all programmed details from the controller, including its house address, and returns it to its factory settings. a) To remove all the Heater details from a Controller (House address unchanged): Enter the install mode on the controller (See Page 7) Removing the heaters from Zone 3 1) Move the selector switch to the Zone 3 position. 2) The display will show the set up for Heater 1 in Zone 3 (Shown as 3: 1 on the screen). 3) If the display has the word Set on the screen then press the right hand Select button to unset. If there is no Set visible then go to 4) below. 4) Press the right hand + button so that heater location moves to 3: 2. If required press the right hand Select button again to unset the heater. 5) Keep pressing the right hand + button so that all heaters in Zone 3 are checked and unset. (There are 15 heater locations in each zone, ranging from 1 to 9 then A to F). Page 14

15 Removing the heaters from Zone 2 1) Move the selector switch onto the Zone 2 position. 2) As with zone 3 above, unset any heaters in zone 2 by pressing the right hand Select button 3) Move between heaters in zone 2 by pressing the right hand + button. Removing the heaters from Zone 1 1) Move the selector switch onto the Zone 1 position. 2) Use the right hand + and right hand Select buttons to unset the heaters in zone 1. b) To remove all the Heater details and generate a new House address: The process described below will remove all the allocated zones and heaters from the controller and create a new randomly generated house address. IMPORTANT Changing the house address on a Controller will mean it WILL NOT work with any heater that has already been programmed. (as described in Section 3 Page 6). Note : 1) Isolate the supply to the Controller. 2) Remove the Controller module from its connection bracket. 3) Switch the Battery Switch on the rear to Off. 4) Put the Controller back onto its connection bracket. 5) Switch the supply on 6) Press the right hand Select and + buttons at the same time and then release (Screen reset) 7) Switch the supply off again. 8) Put the Battery Switch back to its On position. 9) Secure the Controller module back to its connection bracket. 10) Switch the supply back onto the Controller. c) How to Reset the screen : If the screen remains completely blank it can be reset as follows: 1) Press the right hand Select and + buttons at the same time and then release. Notes : Resetting the screen will also return the Zone temperatures and timings to their factory values. (See separate handbook Credanet II A User s Guide ). The current time is reset to Monday 12:00pm. Page 15

16 8. How to reset a heater board If a Heater board has been programmed with the wrong House address then it WILL NOT work correctly. The heater PCB will need to be reset before its house address can be changed. (The Heater board and the Controller MUST have the same House address). a) Checking the house address on a heater PCB : Before resetting a heater board the existing House address on the board can be checked as follows. Put the Controller into Install Mode (See Page 7) and move the slider to the Zone 1 position. Press the right hand + button to find the first unused heater in Zone 1. (The display will change from SET on the screen to having no SET displayed). Switch on the power to the heater being checked and press the Boost button for 2 seconds. (Make sure the power is off to all the other heaters in the system). Now check the Controller again. a) If the display shows the word SET on the screen : Heater PCB does NOT need to be reset. (The Zone / Heater and Type may also change: Go to Section 6 Page 11 Adding a new heater ) b) If the display does NOT show the word SET : Heater PCB must be reset. (See below). b) Resetting the Heater PCB : At the heater : Isolate the supply and remove the panel that gives access to the heater PCB. On the PCB : Remove the two wires from the push on terminals labelled TR. (These are terminated with 2.8mm push on receptacles). Move the two wires from the pair of connections labelled Boost and temporarily push them onto the vacated TR terminals. Heater PCB Switch on the power supply to the heater and then press the Boost button continuously for at least 7 seconds. Isolate the supply to the heater and return the two pairs of cables to their original positions. Fix the panel back to the heater. (The heater PCB has now been reset and can be programmed as described in Section 3 Page 6). Applied Energy Products Ltd. Morley Way, Peterborough. PE2 9JJ.
