PROBLEM SOLUTION
Thermostat is set on AUTO mode,
but the thermostat does not seem
to automatically change-over from
HEAT to COOL or vice-versa.
While adjusting the program
temperature in the HEAT mode,
the program temperature in the
COOL mode also changes by
itself; and/or vice-versa
Cannot change the thermostat
scale from °C to °F or vice-versa.
- The thermostat has a built-in safeguard time delay of 30 minutes to prevent undesirable change-over
sequences from HEAT to COOL or COOL to HEAT. For example, if the thermostat was just running the
cooling system, it will take at least 30 minutes before it changes to heating. You may override this
manually by pressing MODE to change the operation to HEAT or COOL only.
- This will occur when you set the HEAT and COOL program temperatures fairly close to one another. To
prevent a mistake or overlap in temperature settings, the thermostat automatically restricts the two
temperature settings from getting within 3°C (6°F) of one another. The COOL temperature setting will
always be at least 3°C (6°F) higher than the HEAT temperature setting. For example, if the initial COOL
program temperature was set at 24°C (75°F) and you decide to adjust the HEAT program temperature
to 24°C (75°F), the thermostat will automatically push the COOL program temperature up to 27°C (81°F)
to prevent overlapping.
- Selecting the temperature scales is a one-time start-up process. After the first battery installation, you
must HARD reset the thermostat and choose the desired display in °C or °F. Otherwise, you CANNOT
change the temperature scale (°C or °F) later on unless you perform another HARD reset which will
clear all the programs and thermostat settings.
- To perform a HARD reset and select °C or °F, first press and hold the LOCK key. While holding down
the LOCK key, press and release the RESET (R) key located above the battery compartment on the
back. The LCD screen will blank out momentarily. Once the display reappears, then release the LOCK
key. To select °F, quickly press UP or DOWN while the temperature display is flashing. For °C, do not
press any buttons and wait until the temperature display stops flashing.
