4 ST-45 User's Manual I.Description Boiler Temp. Water Heater Temp. Feeder; C.H. Pump; H.C.W. Pump; Fan Button for accessing submenus, confirming settings (encoder) The ST-45 temperature regulator is intended for use with central heating boilers. It is used to control the water circulation pump, hot consumption water pump, floor heating pump, mixing pump, blow (fan) and fuel feeder. The ST-45 regulator features two modules: graphic display panel and control panel. The ST-45 can be used with two optional additional three-way or four-way valve control modules. The regulator has been designed and made for comfort. It is very easy in use. All parameters are adjusted with a convenient knob (encoder). The ST-45 regulator features also a graphic display that shows the current status of the boiler. If the furnace temperature is lower than the setpoint temperature, the regulator is operated in its duty cycle, i.e. the blow is active and the operation time of the fuel feeder is set by the user (both operation and stand-by times are set). If the furnace temperature is equal to or higher than the setpoint -4-

5 TECH temperature, the regulator is operated in its sustain cycle (both standby and sustain mode times are to be set). Please send all comments on the software to the boiler manufacturer. Your controller should be set according to your individual needs, depending on the type of fuel and boiler used. TECH shall not be held responsible for incorrect settings. II.Regulator Functionality This chapter describes regulator functionality, how to change settings and navigate in the menu with the encoder (knob). Depending on the mode the boiler is currently in, the display will show boiler operational parameters. The given mode is selected by the user. While the user is logging in, the display shows the manufacturer and the software version. After several seconds, you can select your language. With this function, you can change the language version. LANGUAGE VERSION Polish English II.1.Main Page During normal operation, the graphic display shows the main page with the following data: -5-

9 TECH II.8.Operation Mode MENU Blow Force Operation Mode Sustain Mode With this function, you can select one out of four operation modes. II.8.a)House Heating If you select this option, the regulator will switch into the house heating mode. The central heating pump starts to run above the pump activation threshold (set to 40 C by default). Below this temperature, the pump is shut off. HOUSE HEATING C.H. H.C.W. II.8.b) Water Heater Priority WATER HEATER PRIORITY C.H. H.C.W. If you select this option, the regulator will switch into the water heater priority mode. Activating the hot consumption water pump will cause the regulator to switch into the water heater priority mode. In this mode, the -9-

10 ST-45 User's Manual (hot consumption water) heater pump is activated until the set temperature is reached. Then, the pump is shut off and the central heating circulation pump is activated. In order to activate the hot consumption water pump, it is necessary to raise the setpoint temperature above the pump activation threshold (the pump activation threshold to be adjusted in the service menu). The temperature can be changed in the H.C.W Set function (see point II 2). In this mode, the fan and the feeder are operated as long as the temperature is below 62 C to prevent the boiler from overheating. Such condition will be maintained until the water heater setpoint temperature is reached. When the temperature is reached, the hot consumption water pump is shut off and the central heating pump is activated. The central heating pump will run until the water heater temperature drops below the setpoint value; then, the central heating pump is shut off and the hot consumption water pump is activated. The hot consumption water priority function consists in that the consumption water is heated up before heating up water in radiators. ATTENTION: the boiler should have non-return valves mounted on the central heating pump and hot consumption water pump circuits. A valve mounted on the pump will prevent the hot consumption water from being discharged from the water heater. A valve mounted on the central heating circuit will not let the hot consumption water move from the water heater into the house circuit. -10-

11 TECH II.8.c) Parallel Pumps In this mode, the pumps run initially in parallel above the pump activation threshold (set to 40 C by default). The central heating pump continues to run and the hot consumption water pump is shut off after the water heater setpoint temperature has been reached. ATTENTION: in this mode, you should mount a three-way valve or a mixing valve that will maintain different temperatures in the water heater and in the house. II.8.d) Summer Mode SUMMER MODE C.H. H.C.W. When the function is enabled, the central heating pump is switched off and the hot consumption water pump is activated above the pump activation threshold (set to 40 C by default). In this mode, the hot consumption water pump continues to run above the pump activation threshold (set to 40 C by default). In the summer mode, the water heater setpoint temperature is to be set. When the summer mode is disabled, the actual temperature of the central heating and two temperatures (actual and setpoint) of the hot consumption water are displayed. -11-

16 ST-45 User's Manual The function is enabled only in the duty mode (i.e. when the boiler temperature is lower than the setpoint temperature). When the boiler temperature fails to rise in the user-defined period, an alarm is activated: the feeder and the fan are shut off (the water pump is switched on and off independently) and the alarm is sounded. The display shows the following message: C.H. Temperature Rise Failed. The alarm can be reset with the encoder. III.4.Room Regulator FITTER S MENU Temperature Alarm Room Regulator Boiler Hysteresis The ST-45 regulator can be connected to a room regulator. In such case, it has a higher priority, which does not apply to heating from the water heater. The feeder, fan and central heating pup run until the temperature set with the room regulator is reached. However, the boiler is limited in its operation by the temperature set with the boiler controller. CONNECTING THE ROOM REGULATOR: the room regulator features a two-wire cable that should be connected to the controller's connection strip, to a terminal labelled as room regulator. ATTENTION: no external voltage can be applied to the room regulator output. III.5.Boiler Hysteresis FITTER S MENU Temperature Alarm Room Regulator Boiler Hysteresis With -16- this function, you can set the hysteresis of the setpoint

17 TECH temperature. This is a difference between the temperature of entering into the sustain cycle and the temperature of returning to the duty cycle (e.g.: when the setpoint temperature is set to 60 C, and the hysteresis is set to 3 C, entering into the sustain cycle will be effected after the temperature reaches 60 C, whereas return to the duty cycle will be effected after the temperature drops to 57 C). III.6.H.C.W. Hysteresis FITTER S MENU H.C.W. Hysteresis Floor Pump Circulation Pump With this function, you can set the hysteresis of the setpoint temperature on the water heater. This is a difference between the setpoint temperature (required by the water heater) and the actual temperature on the water heater (e.g.: when the setpoint temperature is set to 55 oc and the hysteresis is set to 5oC). After reaching the setpoint temperature, i.e. 55 C, the hot consumption water pump is shut off, causing the central heating pump to be activated. The hot consumption water pump will be activated again when the temperature drops to 50 C. III.7.Floor Heating Pump FITTER S MENU H.C.W.

B) Reed Relay Protection With this function, you can set the duration of a complete feed cycle. If the cycle is not completed within the set period, the following message is displayed: Clean Feeder. In this function, data are obtained form the Hall sensor that is located at the feeder. V.Stand-by Mode MENU Service Menu Stand-by Mode -22-

23 TECH In this function, you can switch on or off the stand-by mode for the thermoregulator. All motors of devices (e.g. fan) that are connected to the thermoregulator are stopped. ATTENTION: in the stand-by mode, the power is not cut off completely. Alternatively, you can switch the controller into the stand-by mode by pressing and holding the encoder for several seconds. VI.Protections In order to ensure a safe and faultless operation, the regulator has been provided with numerous protections. In the case of an alarm, an acoustic warning is sounded and the display shows an appropriate message. Press the encoder to restore the controller to operation. VI.1.Temperature Alarm The protection is enabled only in the duty mode (i.e. when the furnace temperature is lower than the setpoint temperature). When the furnace temperature fails to rise in the user-defined period, an alarm is activated: the feeder and the fan are shut off (the water pump is activated regardless of the furnace temperature) and the alarm is sounded. The display shows an appropriate message: If you press the encoder, the regulator will deactivate the alarm. The regulator will return to the previous working mode. VI.2.Thermal Protection The boiler is protected with an additional bimetal sensor (located at the furnace sensor) that deactivates fan and feeder outputs when the -23-

24 ST-45 User's Manual temperature exceeds the critical value, ranging from 85 C and 90 C. This is to prevent water from boiling in the system when the boiler has been overheated or the regulator damaged. With this type of safety temperature protection, the system will return to the initial position (automatically). ATTENTION: in case the thermal relay is damaged, the fan and the feeder are inoperative in both modes: manual and automatic. VI.3.Automatic Sensor Check When the temperature sensor of the central heating, hot consumption water, screw or grate is damaged, an alarm is activated with an additional indication shown in the display, e.g.: C.H. Sensor Damaged: the feeder and the fan are shut off. The pump is activated regardless of the actual temperature. If you press the encoder (this refers to the hot consumption water sensor), the regulator will deactivate the alarm and the controller will return to its normal operation with a single pump. If the central heating sensor or feeder sensor is damaged, the alarm will remain active until the sensor is replaced. VI.4.Anti-Boil Protection This function is used for protecting the boiler against high temperatures [only with the water heater priority function], e.g. when the water heater setpoint temperature is 55 C and the boiler temperature is 62 C, the controller shuts off the feeder and the fan. When the temperature reaches 80 C, the central heating pump is activated. When the temperature continues to rise, the alarm is sounded at 85 C. Such condition may appear when the water heater or the pump are damaged or when the sensor has been improperly mounted. -24-

25 TECH However, if the temperature continues to drop, the controller will activate the feeder and the fan at 60 C and it will continue to operate until the water heater setpoint temperature is reached. VI.5.Temperature Protection The regulator features an additional protection in case the bimetal sensor is damaged. After the temperature exceeds 95 C, the alarm is sounded. The display shows: Temperature Too High The current temperature is read from an electronic sensor and processed by the thermoregulator. When the alarm temperature is exceeded, the fan is shut off and both pumps begin to run in order to distribute hot consumption water throughout the system. VI.6.Fuel Container Protection At the fuel container screw, an additional temperature sensor is mounted. If the temperature rise is high (above 70 C), the alarm is sounded: the feeder is activated for 3 minutes with the fuel being moved into the combustion chamber. The screw sensor protects the fuel from being combusted in the grate. A) Fuel Container Protection (Hall Sensor) The ST-45 controller is additionally protected with a Hall sensor that checks whether fuel is fed from the feeder. If the feeder does not make a complete revolution, the following message is displayed: Hall Sensor Fault. VI.7.Fuse The regulator features two WT 6.3A tube fuses to protect the network. -25-

26 ST-45 User's Manual ATTENTION: it is not advisable to use fuses with higher current ratings. Higher current ratings may cause damage to the controller. VII.Maintenance Before and during the heating season, the ST-45 controller should be checked for any damages in its cables. You should also check if the controller is properly mounted and clean it if dusty or dirty. It is advisable to measure grounding parameters for the motors (central heating pump, hot consumption water pump, fan, feeder, floor pump and circulation pump).
