The first powering up must be performed by CLIMATEWORX authorized
personnel only. Failure to do so may damage the unit and void the warranty.
The main power switch (rotary disconnect) is located on the front of the unit. Series 6, 8, 9 and
P only. For Series 7 and 11 it is located inside electrical panel
Immediately after turning on the main power switch, the control system will perform the
following power up sequence:
1. The control system will generate three short “beep” sound to alert power has been
applied and the unit is about to start.
2. The control system will then perform a self-test and verify all stored setting and data are
within valid range.
3. After the self-test, the control system will count down the programmed “Restart delay”
time and then put the system into normal operation.
