External Smoke Detection

Wiring to Unit

Deluxe Controller

To inhibit operation of the compressor and fan for a

safety shutdown, it is necessary to break the wire (21X)

from the 24Volt transformer to the 1TB1 terminal block.

This can be done with the dry contacts of a relay. When

that connection is opened, it terminates voltage to both

the deluxe controller and the thermostat, which stops/

prevents all control function to the fan and compressor.

UC400B Controller

To inhibit operation of the compressor and fan for a

safety shutdown, it is necessary to break the wire (21A)

from the 24Volt transformer to the UC400B (1U1). This

can be done with the dry contacts of a relay. When that

connection is opened, it terminates the power voltage

to the controller, which stops/prevents all control

function including the fan and compressor.

ZN524 Controller

To inhibit operation of the compressor and fan for a

safety shutdown, it is necessary to break the wire (21X)

from the 24Volt transformer to the 1TB1 terminal block.

This can be done with the dry contacts of a relay. When

that connection is opened, it terminates the power

voltage to the controller which stops/prevents all

control function including the fan and compressor.

Blower Motor Speed-Tap

Retrofit

N N o o t t e e : : For GEH/V 0.5 to 5 ton units only.

Motors installed in the unit include 4-speed or 3-speed

configurations. All voltages include a 4-speed

configuration, with the exception of 380V, 415V, 460V

which contain a 3-speed arrangement and 575V which

contains a 2-speed arrangement. To modify the rpm of

the motor, the following steps must be followed.
