Dampers default to the "OPEN" position
- After a purge delay
- During change over
- Short cycle delays
- When all zone demands are satisfied with
no signals from the thermostats.
From factory the fan coil is pre-wired for two
stage cooling. If single stage cooling is desired
the fan coils controls will need to be re-wired.
Below are the required changes.
Follow the HE-Z Fan coils main Installation
Manual for wiring the PSB to the system.
