Solar differential temperature controller Elios Midi




Digital solar differential temperature controller Elios Midi for solar heating plants: it compares temperatures of fluids in the collectors and the storage tanks and, when the difference is greater than DeltaT, starts the heat exchange through the pump. 3 temperature inputs from NTC sensors and 2 on-off relay outputs SPST. Additional thermostats for driving auxiliary heat sources. All temperatures are displayed. Configuration of 7 different system layouts. Contextual parameters. Minimum thermostat. Offset correction for the measured temperatures. Self diagnostic feature, with visual and acoustic alarms.
