Frost protection thermostat (2-phase) with continuous and switching output
Application
Electronic frost protection thermostat with fully active capillary for monitoring air conditioning systems, heat exchangers, heating registers and other systems against freezing. The limit value undercut is measured at the coldest measuring point on the sensor rod. A safety shutdown occurs in the event of a capillary break, voltage failure or damage.
