The perimeter value is not dependent on the outdoor air temperature value.
Setting a perimeter lockout setpoint prevents activation of the baseboard reheat
when outside air temperatures are above the setpoint.
Present Value
COV Increment (0.5)
-15°F to 120°F or -26°C to 50°C
Resolution 0.1°F /0.1°C
