Azel Technologies Digital Non-Programmable Heat Only Battery Powered Radiant Floor Thermostat

D-28F digital 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 in hydronic radiant floor heating system. 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 limit Battery operated Large LCD display Freeze protection No Leveling Required Contains NO Mercury, environmentally safe Two wire type thermostat Selectable display in °F or °C EEPROM for setting backup ON/OFF switch to shut off relay output Supplied with 10ft....
