This procedure safely prepares the controller before you remove power.

Prerequisites:

  • The controller is powered on. Any running devices (HVAC, boiler, meter, etc) have been set in a standby mode.
  1. First, press and hold the SHUT DOWN button until the SHUT DOWN LED flashes (about 5 seconds). NOTICE! Releasing the button after the flashing LED starts confirms that the button press is intentional.
  • After about 10 seconds, the BEAT LED is no longer lit, indicating that the shutdown preparation process is complete.
  1. Remove power from the controller.
  • Shutdown is complete.
