SEQUENCE OF OPERATION
Cooling Mode
- Thermostat energizes "O" whenever the mode is "Cool'
- Thermostat energizes "Y' and "G" when there is a demand for cooling.
Heating Mode
- Above 40 Deg (adjustable Setup# 312)
- The thermostat will energize "Y" and "G" when there is a demand for heating.
- If the space temperature drops more than 2 deg (adjustable Setup# 309) the thermostat will disable the compressor output "Y" and energize the backup heat output "W".
- Whenever the Backup Heat source energizes it will stay on until the call for heat satisfies (adjustable Setup# 302).
- Below 40 Deg (adjustable Setup# 312)
- The thermostat will energize "W" when there is a demand for heating.
Em Heat Mode
- The thermostat will energize "W" when there is a demand for heating.
