Tekmar Controls 156 Control R-448A verify the hub bore sizeThe Tekmar Controls 156 is a versatile Difference Setpoint Control designed for high efficiency heat transfer between a primary source and a storage tank. Operating on a 24Vac dc power supply, this microprocessor based controller utilizes two 10k sensors to monitor real time temperature differentials (? T). When the source temperature exceeds the storage temperature by the user defined setpoint, the internal 240V, 10A relay closes to activate an on
