Control Wiring - York YCAE065 Manual

Notes
1. Power wiring must be provided through a protect device (fused disconnect switch or circuit breaker)
to the input terminals of the unit in accordance with CE or local code requirements.
2. Every control board is assigned with one ID address. If a single module includes two control
boards, then two ID addresses have to be assigned in the module. The modules above 130 kW
have two control boards in the panel.
3. The maximum quantity of modules above 130 kW combined should be 16. The quantity of
modules in the same communication network is based on the sum total of control boards in the
network.
Disconnecting 230VAC power from the unit, at or below freezing temperatures, can
result in damage to the evaporator and unit as a result of the chilled liquid freezing.
