Thermostats for remote control of Weep or Floor Heat Systems designed for freeze prevention. Standard with a capillary tube so that the unit can be mounted in the pump room and the bulb can be located in an outside area. Temperature differential is + or - (4.5) degrees F. on the Model 2E399.

For Weep Systems use these units with a "normally open" solenoid (not included) to activate the weep water at desired outside temperature.
