COMPACT INSTALLATION MANUAL

Compressor Fixed On Delay Time

The Compressor Fixed On Delay Time will ensure that the

compressor output (B02) is not enabled for 90 seconds

after the control receives a call to start the compressor.

This delay is adjustable from 30 – 300 seconds over a BAS

or a MUI. If the control is in test mode the Compressor Fixed

On Delay Timer will be shortened to 5 seconds.

Compressor Minimum On Delay

The compressor minimum on delay will ensure that the

compressor output is enabled for a minimum of two (2)

minute each time the compressor output is enabled. This

will apply in every instance except in the event the high

pressure switch is tripped or emergency shutdown then the

compressor output will be disable immediately.

Compressor Short Cycle Delay Time

The compressor short cycle time delay will ensure that

the compressor output will not be enabled for a minimum

of five (5) minutes after it is disabled. This allows for

the system refrigerant pressures to equalize after the

compressor is disabled.

Heating Cycle

On a call for heating, the blower enable output and

accessory output 2 will turn on immediately after the

random start delay timer has been satisfied. If the

compressor short cycle time delay has been satisfied,

the compressor will turn on after the blower enable and

accessory output 2 are on and the fixed compressor start

delay timers have been satisfied.

NOTE:

Auxiliary heat output

can be controlled over the BAS.

Set Point Control Mode

In set point control mode the reversing valve output

will be disabled. As the temperature drops below the

heating set point and begins to operate in the heating

proportional band, the compressor (low capacity for

two-stage compressors) output (BO-2) will be enabled.

For units with two-stage compressors, a PI loop in the

programming of the control will determine when the full

capacity compressor output (BO-4) is to be enabled.

The compressor must be operating in low capacity

for a minimum of 30 seconds before the full capacity

compressor output can be enabled. During low capacity

compressor operation the variable speed ECM blower

will operate in medium speed and will operate in high

speed when the compressor is operating at full capacity.

Thermostat Control Mode

In thermostat mode the compressor will be cycled

based on Y1 and Y2 calls from a room thermostat.

When the control receives a Y1 command (BI-7) from

the thermostat the low capacity compressor output

(BO2) will be enabled and the variable speed ECM

blower will operate in medium speed. When the control

receives a Y2 command (BI-8) from the thermostat the

variable speed ECM blower will operate in high speed.

During the heating cycle the reversing valve will be

commanded into the off position.

Cooling Cycle

On a call for cooling, the blower enable output and

accessory output 2 will turn on immediately after the

random start delay timer has been satisfied. If the

compressor short cycle time delay has been satisfied,

the compressor will turn on after the blower enable and

accessory output 2 are on and the fixed compressor start

delay timers have been satisfied.

Set Point Control Mode

In set point control mode the reversing valve output

will be enabled. As the temperature rises above the

cooling set point and begins to operate in the cooling

proportional band, the low capacity compressor output

(BO-2) will be enabled. A PI loop in the programming

of the control will determine when the full capacity

compressor output (BO-4) is to be enabled. The

compressor must be operating in low capacity for

a minimum of 30 seconds before the full capacity

compressor output can be enabled. During low capacity

compressor operation the variable speed ECM blower

will operate in medium speed and will operate in high

speed when the compressor is operating at full capacity.

Thermostat Control Mode

In thermostat mode the compressor will be cycled

based on Y1 and Y2 calls from a room thermostat.

When the control receives a Y1 command (BI-7) from

the thermostat the low capacity compressor output

(BO2) will be enabled and the variable speed ECM

blower will operate in medium speed. When the control

receives a Y2 command (BI-8) from the thermostat the

full capacity compressor output will be enabled and the

variable speed ECM blower will operate in high speed.

During the cooling cycle the reversing valve will be

commanded into the “ON” position.

Variable Speed ECM Blower Operation

Blower speeds will be selected through the user interface or

the facility management system. There will be a total of 12

speeds selectable with only three being selected at any one

time. The lowest numbered speed selection set to ON will

select the low-speed blower setting, the middle selection

set to ON will select the medium-speed blower setting and

the highest selection set to ON will select the high-speed

blower setting. If all selections are set to OFF

Controls - FX10 (optional) cont.
