SKU: TEKMAR157
Manufacturer: TEKMAR
Price: $224.85

The Tekmar Differential Setpoint Solar Control 157 is designed to operate a variable speed pump to transfer heat from a heat source such as a solar panel to a storage tank. Varying the speed of the pump provides fast and accurate temperature control to maintain the target temperature difference ÄT. The Tekmar 157 Solar Control has additional minimum and maximum setpoints to turn off the pump when heat transfer is no longer desirable. Potential applications for the Tekmar 157 include using solar collectors / panels or a wood boiler as a heat source. Included with this control is three Tekmar 071 Sensors which are 3/8 inch OD and 3/4 inch long. Some Solar Panel and Solar Storage Tanks have smaller wells and may require the purchase of Tekmar 079 Sensors.
