Product Overview

D-508F UNIVERSAL MULTI-DISPLAY RADIANT FLOOR HEATING THERMOSTAT
FEATURES:
§ 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
§ Contemporary design
§ 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

AZEL
TECHNOLOGIES INC.
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). 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.
