Electrical Shock Hazard

Front Desk Control Terminal

The Friedrich PZ model PTAC has built-in provisions for connection to an

external switch to control power to the unit. The switch can be a central

desk control system.

For front desk control operation, connect one side of the normal open

switch to the R terminal and the other to the FD terminal.

The control logic as below:

(a). Turn ON unit: short R and FD then release for one time within 5s.

(b). Turn OFF unit: short R and FD then release for twice within 5s.

(c). Force unit shut down for one time: short R and FD short over 5s.

NOTE: After forced shut down, you can turn on the unit again by control

panel.

NOTE: The desk control system and switches must be field supplied.

Energy Management

Sometimes known as Front Desk Control, an input is provided so that the

unit can be manually disabled from a remote location. If the unit detects

24Vac on this input, it will automatically turn itself off. If no voltage is

detected on the input, the unit will run normally.

NOTE: It is the installer's responsibility to ensure that all control wiring

connections are made in accordance with the installation instruc-

tions. Improper connection of the thermostat control wiring and/or

tampering with the unit's internal wiring can void the equipment

warranty. Other manufacturer's PTACs and even older Friedrich

models may have different control wire connections. Questions

concerning proper connections to the unit should be directed to

Friedrich.
