Range:

  • ±7ºF in 1 degree increments
  • ±4ºC in 0.5 degree increments
  • Default: 0 degrees
Span

Temperature variance before taking action.  This value determines the amount of temperature variation allowed before calling for heat or cooling. Example: a span of 1ºF with a set point of 70ºF will allow the room temperature to swing between 69ºF and 71ºF without taking action.

  • Range: 0.5 – 2.0ºF in 0.5 degree increments
  • 0.25 – 1.0ºC in 0.25 degree increments

PAIR

This menu item allows the Optima ZigBee thermostat to be connected to a compatible connected home system. Pairing the OPTIMA to a connected home system is a coordinated effort between the two systems. Following are general steps for the pairing process.

  • Prepare connected home system to add a thermostat.
  • Go to the PAIR menu item on the OPTIMA thermostat (Hold Mode down for 3 seconds until CLOCK is displayed.  Use the +/- to scroll until PAIR is displayed).
  • Press MODE to select pairing mode. Display will show WILL PAIR.
  • Press MODE again to enter pairing mode. Display will show the number 10 and Pairing.
  • Wait for the connected home system to recognize the thermostat. The thermostat will blink IDENTIFY and return to the Home Screen when the thermostat has been added to the system. The blinking IDENTIFY will go away after 3 minutes.
Update

This menu item initiates a check for new firmware on the connected home system and updates the firmware automatically if one is found.
