Operation

Cooling sequence of operation

The factory Unit Control Board (UCB) refers to either

the Everyday Thermostat Control (ETC) board, or the

Smart Equipment™ control board. Both the ETC and

the Smart Equipment™ control boards operate in

similar fashion, and are described below. When a

difference in operation between the ETC and Smart

Equipment™ board exists, a description of both

operations will be described.
With a demand for first stage cooling either from a

thermostat or space sensor, the low-voltage control

circuit to "C1" and "G" is completed. For first stage

cooling, the compressor is energized and the 1st

stage operates. The UCB will energize the VFD

equipped blower motor at low speed as set in the

Smart Equipment™ control. When the thermostat

calls for the second stage of cooling, the low-voltage

control circuit to "C2" is completed. The control

board energizes the 2nd stage of the compressor.

If there is an initial call for both stages of cooling,

the UCB will delay energizing the 2nd stage of the

compressor by 30 seconds in order to avoid a power

rush. Once the thermostat has been satisfied, it

will de- energize C1 and C2. If the compressor has

satisfied the minimum run time (3 min default), the

compressors and condenser fans are de-energized.

Otherwise, the unit operates until the minimum

run has been completed. Upon the compressor

de-energizing, the blower is stopped following the

elapse of the fan off delay for cooling.
The call is passed to the Unit Control Board (UCB),

which then determines whether the requested

operation is available and, if so, which components

to energize.
If at any time a call for both heating and cooling are

present, the heating operation will be performed.

If operating, the cooling system is halted as with

a completion of a call for cooling. Heating always

takes priority.

Continuous Blower

By setting the room thermostat fan switch to "ON,"

the supply air blower will operate continuously.

Intermittent Blower

With the room thermostat fan switch set to "AUTO"

and the system switch set to either the "AUTO" or

"HEAT" settings, the blower is energized whenever

a cooling or heating operation is requested. The

blower is energized after any specified delay

associated with the operation.

When energized, the indoor blower has a minimum

run time of 30 seconds. Additionally, the indoor

blower has a minimum off delay of 10 seconds.

No Outdoor Air Options

When the thermostat calls for cooling, the low-

voltage control circuit from “R” to “Y1” and “G”

is completed. The compressor and condenser fan

motor are energized. After completing the specified

fan on delay for cooling, the UCB will energize the

blower motor.
Once the thermostat has been satisfied, it will de-

energize Y1. If the compressor has satisfied its

minimum run time, the compressor and condenser

fan de-energize. Otherwise, the unit operates the

cooling system until the minimum run time for

the compressor has been completed. After the

compressor de-energizes, the blower is stopped

following the elapse of the fan off delay for cooling.
To be available on the ETC and Smart Equipment™

controller, a compressor must not be locked-out

due to a high or low-pressure switch or freezestat

trip. Additionally on the Smart Equipment™

controller, the Evaporator Low Limit sensor (EC1)

detecting a temperature below 26° F and the anti-

short cycle delay (ASCD) must have elapsed.

Economizer With Single Enthalpy Sensor for ETC,

and Economizer With Dry Bulb Sensor for Smart

Equipment™

When the room thermostat calls for cooling, the low

voltage control circuit from “R” to “G” and “Y1” is

completed. The UCB energizes the blower motor

(if the fan switch on the room thermostat is set in

the “AUTO” position) and drives the economizer

dampers from fully closed to their minimum

position.
If the enthalpy sensor for the ETC, or Dry bulb

temperature sensor for Smart Equipment™ reads

outdoor air is below the setpoint for their respective

controller, “Y1” will energize the economizer.

The dampers will then modulate to maintain a

constant supply air temperature as monitored

by the discharge air sensor. If the outdoor air is

above the enthalpy setpoint for ETC or dry bulb

temperature setpoint for Smart Equipment™, “Y1”

energizes the compressor and condenser fan motor

only.
