Description for Tekmar 156

Control Description The Difference Setpoint Control 156 is designed to operate an on/off pump to transfer heat from a heat source to a storage tank. The control operates based on a setpoint temperature difference (ΔT). The relay turns on when the ΔT rises above the setpoint and turns off when the ΔT falls below the setpoint less the differential. The Source Minimum and Storage Maximum settings turn off the relay when heat transfer is no longer desirable. Potential applications include using solar collectors or a wood boiler as a heat source.

        Comments about Difference Setpoint Control - On/Off:

        The Tekmar 156 is the perfect control for a home based solar water heating system. Mounted next to my house thermostat, the read-outs tell me everything I want to know about how my system is operating, and at the same time completely automating the control of my circulating pump for maximum efficiency. Once installed, you just sit back and let the control run the system.
