MODEL AGZ CHILLERS

Cycle Timers

A minimum time between starts of the compressor and a

minimum time between shutdown and start of the compressor

shall be enforced. The time values are determined by the

Start-start Timer and Stop-start Timer setpoints.
These cycle timers should not be enforced through cycling of

power to the chiller. This means that if power is cycled, the

cycle timers should not be active.
These timers may be cleared via a setting on the controller.

Condenser Fan Control

Condenser fan control should stage fans as needed any time

compressors are running on the circuit. All fans and solenoid

valves will be off when the circuit is in the off and preopen

states. Condenser fan digital outputs will be turned on or

off immediately for condenser stage changes. Condenser

solenoid valve outputs will turn on immediately when a stage

up requires the output to turn on, but will have a delay for

turning off during a stage down. This delay is 20 seconds. If

the circuit shuts off then the condenser solenoid valve outputs

will turn off without a delay.

Condenser Staging

Condenser staging will use up to 5 digital outputs for control of

condenser fans and a digital output for control of a condenser

solenoid valve. When equipped with condenser fan VFDs, the

speed signal(s) also starts and stops the fan that is connected

to the VFD. The total number of fans on shall be adjusted

with changes of one fan at a time. The tables below show the

outputs energized for each stage.
