  • The DST-932 model is conceived to control the Solar Heating Systems. The DST-932 drives a pump in order to warm up the water into a storage tank (by the sun energy). The controller reads the temperatures of the storage tank (T1) and of the collector (T2), when this differential temperature (T2-T1) is higher than a set value (dt) it will switch on the water pump. It is possible limit the maximum temperature of the storage tank and also activate a freeze protection function. By switching to manual mode it allows the test of the heating system. A universal sensor is supplied with the control. This solid state temperature sensor probe can be extended up to 500 hundred feet.
