Calibrating the Internal Thermometer
The internal thermometer in the heater can be re-calibrated to match the room
thermometer if it is not sufficiently accurate the way the heater arrived from the
factory. This procedure can be completed directly with the PCB controls on the
front panel:
1.
Turn the heater on
.
2.
Determine what the heater thinks the room temperature is (base-line
temperature) by
pressing the “up” and “down” buttons at the same time
.
The heater will display the temperature that it thinks the room is at. This
may or may not correspond with the wall thermostat setting (or another
reference thermostat that you are using). If the heater thermostat does
not register the same as the wall thermostat, this is what you are about to
change.
3.
Release the buttons and wait 15 seconds
for the heater to return to its
regular function.
4. To continue with the re-calibration,
press “up” and “enter” at the same
time and hold until the heater displays what it thinks the room temperature
is. The display will begin to flash this number.
5.
Press “enter”
again.
Now, press the “up” or “down buttons until the
number on the heater’s display screen matches the room temperature
of the room thermometer on the wall.
Once you are satisfied with the
number on the display screen of the heater,
press “enter” again
.
6. Allow the heater to return to its original function. The display will now
revert to a temperature setting that is derived from the new base-line
temperature. Now, press the “temperature” button and when the display
starts flashing, adjust the room temperature to your desired setting by
pushing the appropriate “up” or “down” button. Once the display matches
your desired room temperature, press the “enter” button to establish
the new set point for the temperature which takes the heater out of the
temperature calibration mode.
This entire procedure can be followed skipping step 1 and using the temperature
setting on any wall thermostat instead of the temperature setting on the internal
thermometer in the heater. Remember, the internal temperature measurement on
the thermostat is only your starting reference point and it is strictly arbitrary. It is
set at the factory and is usually within 2 degrees of reality.
By following this procedure, you are setting the unit to precisely match the wall
thermostat rather than the factory installed thermostat setting. Either set-point is
fine depending upon the customer’s preference.
