Honeywell’s TL7235A thermostat can be used to operate an electric
heater to control the room temperature.
* The thermostat displays the percentage of heater duty cycle required to maintain
the desired temperature. For example, if the heater is activated 40 percent of the
time, is displayed.
• To remove the control module from its
power base, loosen the captive screw
underneath the thermostat and pull the
two halves apart as shown.
• To install the control module onto its
power base, reverse the above proce-
dure.
NOTE: Always keep the thermostat's vents clean and unobstructed.
You can select the temperature display (°F or °C) via
a DIP switch (S1) on the back of the control module.
As soon as the thermostat is powered, it undergoes a
series of tests before displaying the actual temperature.
The measured temperature is below 32°F (0°C).
Heating is activated.
The measured temperature is above 122°F (50°C).
The display illuminates for 5 seconds when the backlight button is
pressed. When either of the buttons is pressed, the display
illuminates for 10 seconds.
The thermostat normally displays the actual temperature. To view
the setpoint, press one of the buttons once. The setpoint
appears for 5 seconds. To change the setpoint, press one of the
buttons during the setpoint display. To scroll faster, hold the
