MINIMUM OFF timer
Once a heating or cooling demand is satisfied on the thermostat, the MINIMUM OFF timer is set to a 300-second
value (5 minutes) and then begins to count down each second. Heating and cooling outputs are de-energized the
entire time that this timer has a value greater than 0.
MINIMUM ON timer
Once a heating or cooling output becomes active, the 5-minute MINIMUM ON timer begins to count down. The
output will not de-energize until the timer reaches zero and the demand is satisfied. If the user changes the
setpoint to satisfy the demand, the 5 minute minimum on time is ignored and the heating or cooling equipment
turns off.
Non-volatile memory
The thermostat can store settings in non-volatile memory to ensure that settings remain the same after a power
outage (either intentional or unintentional). Items stored in non-volatile memory include:
• Installer settings
• Menu settings
• Program schedule
• Date and time
• Software information
• Dealer information
• Fault and system event information
Deadband
The thermostat controls the number of degrees (°F or °C) between the heating and cooling setpoints. If the user
changes a setpoint that violates the deadband requirement, the opposite mode setpoint is “pushed” to enforce
the deadband. The deadband setting is fixed at 2°F.
