Application

The Two Heating Circuit Compensator 3634 is a microprocessor based weather compensator. It provides separate compensation for the boiler loop and mixing loop, making it the ideal for radiator / floor heating combination systems. For a mixing device, the 3634 can use either a floating action 3 or 4 way mixing valve or a variable speed injection pump (see Essey E 021). The 3634 is also capable of controlling a DHW cylinder temperature by either reading a DHW demand signal (240 Vac) from the DHW Cylinder Stat or measuring the DHW temperature by immersing an optional DHW Sensor directly into the DHW cylinder.

The 3634 has a large Liquid Crystal Display (LCD) in order to view system status, operating information, control settings and monitor system performance. It has capabilities of tracking important service information such as DHW cylinder temperatures, outdoor and system high and low temperatures and boiler running times and firing cycles. Several energy saving and system protection features have been incorporated into the 3634 such as Warm Weather Shut Down (WWSD), DHW post purge, system setback, DHW priority, Morning Boost, Soft Start, Auto Differential, Boiler Return Protection and Pump Exercising.

The 3634 achieves zone room temperature control by either reading a powered signal from multiple thermostat controlled zone valve end switches or a Demand output from the Wiring Center or by reading the tekmar RTU 062. Night setback is achieved by interrupting the 2614's Boiler Demand input signals or by providing a night setback signal when using RTU 062. For more detailed zoning and setback applications refer to the tekmar 'A' brochures.
