Azel D-508F digital non-programmable heat only thermostat is designed to control either ambient(air) temperature (A Mode) or floor temperature (F Mode) or a combination of ambient temperature with floor temperature limits(AF Mode). Generally, in radiant heating applications you want to use a non-programmable thermostat as your do not want to turn up and down radiant heat systems as you would other hydronic heating systems.

An auxiliary remote sensor is provided to measure slab temperature in order to control the floor temperature(within maximum and minimum limits in AF Mode). It can also be used for sensing the outdoor temperature in A Mode.

Azel Technologies Digital Non-Programmable Thermostat - D508F Features

  • Large LCD display
  • Easy-to-Read Digital Multi-Display with backlit which provides constant readout of two sensor temperatures(eg. ambient and floor) and setpoint simultaneously, functional status and control settings.
  • Three temperature control modes: A Mode : controls ambient temperature F Mode : controls floor temperature. Also displays current ambient temperature. AF Mode: controls the ambient temperature and maintains the floor temperature within the desired minimum limit for floor warming and maximum limit for protecting floor coverings. Also, displays current floor temperature.
  • QuickSet feature allows instant setpoint adjustment without entering the SETTING mode
  • Easy installation and setup
  • Selectable display in F or C
  • On/Off switch to shut off relay output or shutdown the thermostat at end of heating season for added security
  • EEPROM memory retains control settings in the event of a power failure
  • Lockout mode to prevent tempering by unauthorized personnel
  • Sensor failure and out of range indications
  • One stage heating application
  • Backlit option: Auto (60 sec.)/OFF/ON
  • Supplied with P-01 floor sensor
  • Battery free
  • RoHS(Restriction of Hazardous Substances) compliant means this thermostat is Eco- friendly
