Advanced 2-Stage Heating or Cooling Systems
INSTEON Wireless Thermostat does not have the ability to operate first or second stages of Heat or Cool
directly but can instruct INSTEON Thermostat to operate the HVAC. First and second stage of Heat or
Cool engages under the following conditions when INSTEON Thermostat is connected to the HVAC:
• INSTEON Thermostat setpoint is set at 5 °(F or C) or more below ambient in Cool mode and 5 ° (F
or C) or more above ambient in Heat mode
- Heat mode setpoint is 80°, ambient is 72° = first and second stage engaged
- Cool mode setpoint is 78°, ambient is 84° = first and second stage engaged
• INSTEON Thermostat has been active in Heat or Cool for longer than 10 minutes and did not
reach setpoint
- Heat mode ran for 10 minutes and did not reach setpoint = second stage engaged
- Cool mode ran for 10 minutes and did not reach setpoint = second stage engaged
Note: It is possible for INSTEON Thermostat to occasionally engage and disengage second stage during
a single heating or cooling cycle as variables are met.
