LOW VOLTAGE ELECTRICAL CONNECTIONS - ROOM THERMOSTAT (Optional) A low voltage (24VAC) room thermostat can be used for room temperature control with the ThermElect Hydronic system. If so, Steffes recommends using a digital LOW VOLTAGE CONNECTIONS thermostat. To initiate a heat call, the system needs a switch HYDRONIC HEATING closure from R to H. -
Page 18: Air Conditioner/Heat Pump Interface
AIR CONDITIONER/HEAT PUMP INTERFACE The ThermElect Hydronic system can be used in conjunction with an air conditioner or a heat pump. Contact Steffes for more information. PRESSURE RELIEF VALVE INSTALLATION WARNING Risk of explosion. Can cause injury or death. The factory supplied pressure relief valve MUST be connected to the system with the supplied fittings. -
Page 19: Plumbing
PLUMBING The ThermElect Hydronic system should be plumbed with a primary loop and secondary (zone) loops. The primary loop needs to consist of a minimum of 12’ of 1.25” pipe. The heat exchanger inlet and outlet are 1.5” diameter, reducers will be required if 1.25” pipe is elected for the primary loop. The secondary (zone) loops require additional pump(s) to operate effectively. - Page 20 Heat Exchanger Flow and Restriction Properties Restriction 80 Restriction 150 F Water Velocity (Feet/Sec) 50% Propylene Glycol (Feet of Head) (Feet of Head) 24.5 CAUTION Heat Exchanger Specifications FREEZE PROTECTION: Risk of property damage.

If an Er03 is displayed, check the circuit. - Page 31 Error Code Description Discharge air sensor temperature is out of normal operating range. This can indicate an open sensor, a short in the wiring, or a circuit board which is out of calibration. Take an ohm reading across the sensor to ensure proper operation, check the wiring, and verify the value in L035.
- Page 32 Management Controller and make sure J1 is “ON” and J2 is “OFF”. Verify that the value in L053 is correct for the application. There is no communication occurring with the Steffes Time Clock Module. If this module is installed, the interface cable or the time clock module may be defective. If the Time Clock Module is not being used, verify the value in L035.
