Balancing a System by Temperature Difference (INFO 7.) Mixing ontrol Stk# 3320 Setting up 3320 controller injection system. Ensure the slab is up to temperature before setting the balancing valve for the injection circuit. 2. Ensure boiler is at operating temperature 3. reate heat demand situation at the controller by turning up thermostats or opening window etc.. alculate the target supply water temperature using the graph on page. 5. emove the motor from the injection zone valve 6. Ensure there are some wild loops in the system so the mixed water is being cooled. 7. Fully close the balancing globe valve and then gradually open the balancing valve until you obtain the target supply water temperature. The supply water temperature can be read on the controller display. 8. eplace motor on injection zone valve and remove handle from the balancing valve. The following items are essential for creating a balanced system. The balancing pipe size must be the same size as the system loop. 2. You must always use a globe valve for balancing. 3. The pressure drop across the injection loop should be as low as possible. This is achieved by ensuring that the distance between the supply and return on the injection loop are no more than pipe diameters apart and that the injection loop is perpendicular to the boiler and system loops.. There should always be thermal drop (minimum 6" / 00 mm) on the injection loop return.

Sequence of Operation Mixing ontrol Stk# 3320 The 3320 provides full outdoor reset tough a modulating injection valve to a hydronic heating system. The 3320 may obtain a heat demand from the Stat control or from common thermostats to provide mixing to the system. The control provides boiler return protection tough the mixing device, in order to prevent boiler flue gas condensation. The 3320 has capabilities of controlling the room temperature of a single zone tough an indoor sensor, or provide slab temperature limitation tough a slab sensor. Demands: In order to provide a heat demand to the 3320, 2 V (ac) must be present in terminals and 2 ( Dem) or 2 V (dc) must be present in terminals 3 and (D Dem). Once the control registers a heat demand and the outdoor temperature is below the (warm weather shut down), the system pump is turned on and the injection valve may be modulated in order to provide full outdoor reset. The boiler relay turns on, once the valve is 25 open, or the boiler return temperature is below the Boil ET setting. Once enabled, the boiler relay will stay on for at least 3 minutes or until the heat demand is removed. Indoor sensor operation: The control may control the room temperature of a single zone tough an indoor sensor. The control must have 2 V (ac) in the Demand terminals or 2 V (dc) in the D Demand terminals. An indoor sensor should not be used together with multiple zones and thermostats as the indoor sensor is the controlling factor. The IND/FLO setting must be set to the IND position in order for the control to operate in this mode. Once the outdoor temperature drops below the setting and the zone requires heat, the control will turn on the system pump. The injection valve will be modulated based on the OOM, IND DSN, OUT DSGN, and DSGN WT settings. (These settings establish the starting and design conditions of the heating curve. The control then automatically calculates the heating curve ratio). If the zone requires more heat the supply water temperature is shifted upward and if it needs less heat the temperature is shifted down. Slab temperature limiting: If the IND/FLO setting is set to FLO, the control assumes a slab sensor has been installed in a slab. When a heat demand is present and the control is not in, the control will maintain the slab temperature between the FLO MAX and FLO MIN settings. The supply water temperature fluctuates based on the outdoor temperature. return protection: The control has an optional boiler return sensor input in order to provide boiler return protection. When the return temperature is below the Boil ET setting, the control modulates the injection valve towards the closed position in order to allow the boiler temperature to raise and prevent flue gas condensation. : The control has a maximum supply setting which limits the supply water temperature to the system. ON: The percentage that the injection valve is open before activating the boiler. High Mass = 50-60 Low Mass = 0-50 an be adjusted to suit system (0-70 ). OFF: The percentage that the injection valve is open before deactivating the boiler. Normally 30; can be adjusted to suit system (0-60 ). On Time: This is the minimum time the boiler enable will send a signal to activate the boiler. This should be 3 min for a high mass boiler and 0 min for a low mass boiler. This is a guide only and should be confirmed with the boiler manufacturer. Normally 3 min; can be adjusted to suit system (0 to 8 min). Off Time: This is the minimum time before the boiler can be fired again after the boiler enable has been deactivated. This should be 3 min for a high mass boiler and 0 min for a low mass boiler. Again, check with the boiler manufacturer.normally 3 min; can be adjusted to suit system (0 to 8 min). Purge: A purging time may be set in order to keep the system pump running for an additional period of time after a demand is removed. This setting may also be set to Off if no purging is required. Exercise: The control includes an exercising feature which exercises the system pump for about 20 seconds. The injection valve is also exercised, however not during pump exercising. The frequency in which the system pump and valve are exercised is adjusted tough the EXEISE adjustment. Flush: Some applications which use a DHW tank for dual purpose (heating and DHW generation), require flushing of the heating system in order to prevent bacteria growth. The 3320 will flush the system by turning on the system pump as well as the injection valve for 20 minutes every 6 days. The FLUSH setting must be set to ON. Note: recommends isolation of domestic water tough a heat exchanger. Direct DHW discharge into the floor may not be allowed in some jurisdictions. Please confirm your local codes 5
Sequence of Operation Mixing ontrol Stk# 3320 Monitor : The 3320 has a Monitor menu which displays Hi and Lo temperatures, pump running time, and some misc. messages. OUT HI / LO - Hottest and coldest outdoor temperature MIX HI / LO - Hottest and coldest supply temperature PUMP - Number of hours the pump has run BOILE - Number of hours the boiler has been called for heat OOM HI / LO - Hottest and coldest room temperature. Only displayed when using an indoor sensor OP E - This message appears in areas where electromagnetic noise may be interfering with the control, and refers to the number of times the control had to reset itself. NON-OP - This message shows the number of times the power has been interrupted. Each of these above values may be cleared by pressing the up and down keys simultaneously. Test button: When the Test button is pressed, the control operates each device (pump, injection valve, boiler) for 0 seconds. Each step may be skipped by pressing the Test again. Max heat: The control has a max heat feature which operates the system at maximum settings. This feature is typically helpful during system start up. When the Test button is pressed for 3 seconds the control flashes the Test light and displays MAX HEAT NO. The user should then select tough the arrow keys --> YES. If a heat demand is present, the control will turn on the system pump, the boiler relay and will increase the mixing output to target the temperature. minimum temperature is ignored. This feature will be enabled for 2 s or until either the,, or Test button is pressed. The amount percent output may be adjusted tough the Up and Down keys. The Test light will flash during max heat operation. Units: The 3320 may display temperatures in or F. ontrast: The contrast on the new LD (Liquid rystal Display) may be adjusted.

The control was unable to read the indoor or slab sensor due to a open circuit. The control operated on the heating curve only. The indoor sensor or slab sensor is ignored. Additional Troubleshooting If the air temperature in the room is too cold, the control will shift the heating curve (and point) up, which raises the supply water temperature until the room warms up. If the air temperature in the room is too warm, the control will shift the heating curve (and point) down, which lowers the temperature until the room cools down. A very cool room temperature can shift the curve far enough to bring the control out of at warm outdoor temperatures. A very warm room temperature can shift the curve far enough down to put the control into at cool outdoor temperatures. In an injection system it is important to maintain flow past the supply water sensor so that the reset control will be able to read the correct temperature and the pump will keep the water well mixed. See drawing on page two for locations of all the sensors and piping sequence. Other variations of this control can be acquired from your local ep or from the tee main offices (see back cover). 20

Press the control release clip on the base inside the wiring chamber and slide the control upward. The control lifts up and away from the base. The base is ready for mounting. Mounting the Universal 3007 Note: this sensor is designed to mount on a pipe or in a temperature immersion well. The sensor can be strapped directly to the pipe using the cable tie provided. Insulation should be placed around the sensor to reduce the effect of air currents on the sensor measurement. The Universal 3007 should be placed downstream of a pump or after an elbow or similar fitting. This is especially important if a large diameter pipes are used as the thermal stratification within the pipe can result in erroneous sensor readings. Proper sensor location requires that the fluid is thoroughly mixed within the pipe before it reaches the sensor. If possible, the sensor should be placed 2" to 6" (300 to 00 mm) downstream of the pump discharge. Slab s 30072 & 30073 Note: Proper placement of this sensor is critical for correct operation of the control. This sensor is designed to be embedded in the slab material. The sensor can also be installed an a plastic or metal conduit embedded in the slab. If there is ever a sensor failure, this allows the sensor to be removed and replaced. The sensor should be placed " (25mm) below the slab surface and /2 way between the pipes. /2 way between the pipes " (25mm) 2
Assembly / s Mixing ontrol Stk# 3320 Indoor 30076 The Indoor 30076 includes a 0 kω thermistor which provides an accurate measurement of indoor temperature. The 30076 sensor can be mounted directly on the wall using two #6 - " screws. 30070 The 30070 includes a 0 kω thermistor which provides an accurate measurement of the outdoor temperature. The 30070 sensor is protected by a white U.V. resistant PV plastic enclosure. Universal 3007 The 3007 Universal has a zinc sleeve for fast response and a wide operating range. This sensor can be used in a multitude of applications. 0 0 0 5 2 Slab s 30072 and 30073 The Slab s 30072 and 30073 have a PV plastic sleeve which is designed for use in soils or concrete. The 30072 is supplied with 20 ft (6m) and the 30073 is supplied with 0 ft (2m) of 2 conductor cable. Testing Instructions A good quality test meter capable of measuring up to 500 kω ( kω = 000 Ω) is required to measure the sensor resistance. In addition to this, the actual temperature must be measured with either a good quality digital thermometer, or if a thermometer is not available a sensor can be placed alongside the one to be tested and the readings compared. First measure the temperature using the thermometer and then measure the resistance of the sensor at the control. The wires from the sensor must not be connected to the control while the test is performed. Using the chart below, estimate the temperature measured by the sensor. The sensor and thermometer reading should be close. If the test meter reads a very high resistance, there may be a broken wire, a poor wiring connection or a defective sensor. If the resistance is very low, the wiring may be shorted, there may be moisture in the sensor or the sensor may be defective. To test for a defective sensor, measure the resistance directly at the sensor location. Do not apply voltage to a sensor at any time as damage to the sensor may result.
