NON-PROGRAMMABLE DIGITAL THERMOSTAT FOR RADIANT FLOOR HEATING (BATTERY OPERATED) For Sale

D-28Fdigital hydronic radiant floor heating thermostat is specifically designed for Radiant Floor Heating Systems. It is so flexible that it can be used to control either air temperature (A Mode) or floor temperature (F Mode) or a combination of air temperature with floor temperature limits(AF Mode). An auxiliary remote sensor is provided to measure slab temperature in order to control the floor temperature within desired maximum and minimum limits.

FEATURES:

• Large LCD display
• Dual sensor control modes:Mode A: Room sensor for Heating/Cooling.Mode F: Floor sensor with maximum and minimum limits. Mode AF: Room sensor and Floor sensor combined to control the ambient temperature and maintains the floor temperature within the desired maximum limits.
