IMPORTANT:
The party in charge of the supply of the condenser and of its refrigerant piping is responsible of implementing all the required
protections to comply with the PED requirements for the design pressure of the condenser installed.
IMPORTANT:
The only electrical signals that the Trane CCUF unit provides to the remote condenser are:
- Enabling signal
- 0-10 V modulating signal
