FORM 150.68-ICOM1 

ISSUE DATE: 10/15/2020

Units without a hydro kit. The flow switch –XTBC1 

terminals 13 & 14 is open and the unit will not run or if 

running, stops. A stop due to the flow switch opening is 

recorded in history as a UNIT FAULT: FLOW SWITCH 

OPEN, but no remote alarm is given.

SYS X SYS SWITCH OFF 

 

The system switch under OPTIONS is turned off. The 

system will not be allowed to run until the switch is 

turned back on.

SYS X NO COOL LOAD   

 

This message applies to the cooling mode only. The 

chilled liquid temperature is below the point (determined 

by the SETPOINT and RANGE) that the microprocessor 

will bring on a system or that the microprocessor has 

not loaded the lead system far enough into the loading 

sequence to be ready to bring the lag system on. The 

lag system will display this message until the loading 

sequence is ready for the lag system to start.

SYS X NO HEAT LOAD   

 

This message applies to the heating mode only. The hot 

liquid temperature is above the point (determined by 

the SETPOINT and RANGE) that the microprocessor 

will bring on a system or that the microprocessor has 

not loaded the lead system far enough into the loading 

sequence to be ready to bring the lag system on. The 

lag system will display this message until the loading 

sequence is ready for the lag system to start.

SYS X COOLING RUN  X 

 

SYS X HEATING RUN  X 

 

SYS X DEFROST RUN  X 

 

Indicates that the respective system is running in cooling, 

or heating or defrost due to demand. The X will be 

replaced with the number of compressors in that system 

that are running.

SYS X AR TIMER XXX S 

 

Shows the amount of time left on the respective systems 

anti-recycle timer. This message is displayed when the 

system is unable to start due to the anti-recycle timer 

being active.

SYS X AC TIMER XX S  

 

The anti-coincident timer is a software feature that 

guards against 2 systems starting simultaneously. 

This assures instantaneous starting current does not 

become excessively high due to simultaneous starts. 

The microprocessor limits the time between compressor 

starts to 1 minute regardless of demand or the anti-

recycle timer being timed out.

SYS X DSCH LIMITING  

 

Discharge pressure limiting is in effect. The limiting 

pressure is a factory set limit to keep the system from 

faulting on the high discharge pressure cutout due to high 

load or pull down conditions. When the unload point is 

reached, the microprocessor will automatically unload 

the affected system by de-energizing one compressor.

The discharge pressure unload will occur when 

the discharge pressure gets within 10 psig of the 

programmed discharge pressure cutout. This will only 

happen if the system is fully loaded and will shut only 

one compressor off. Discharge limiting will prevent the 

last compressor in a system from starting if the discharge 

pressure is above 85% of the programmed discharge 

pressure cutout. Reloading the affected system will occur 

when the discharge pressure drops to 85% of the unload 

pressure and 10 minutes have elapsed.

SYS X SUCT LIMITING  

 

Suction pressure limiting is in effect. The suction 

pressure limit is a control point that limits the loading 

of the lag compressor in a system when the suction 

pressure drops to within 15% (cooling) 20% (heating) 

above the suction pressure cutout. In heating/defrost 

modes the actual suction pressure cut-out value is used. 

(Refer to Fault Status Messages Section for details of 

actual suction pressure value calculation from discharge 

pressure).The system will be allowed to load after 60 

seconds and after the suction pressure rises above the 

suction pressure limit point.
