Table P: Error messages generated from the VERSA IC
®
Control Board
Error Message Timeout Description Troubleshooting
CTRL SETUP 3 sec
EEPROM setup block read error at power up. Factory defaults
are reloaded. Operation stops until all adjustments are
checked.
Check all SETUP items (Restoring factory defaults at VERSA
®
may clear
these faults)
SUPPLY ERR 3 sec
System supply sensor is shorted or has an open circuit. The
control will cease operation.
Check supply sensor
Check supply sensor wiring
DHWSUP ERR 3 sec
Plant sensor is shorted or has an open circuit. The control will
cease operation.
Check Aux1 sensor
Check Aux 1 sensor wiring
OUTDOOR ERR 3 sec
Outdoor air sensor is shorted or has an open circuit. The con-
trol will continue to operate assuming an outdoor temperature
of 32°F
Check outdoor air sensor
Check outdoor air sensor wiring
DHW ERR 3 sec
Indirect DHW sensor is shorted or has an open circuit. The
control will cease operation for indirect DHW, but will continue
to operate as required for system heating.
Check DHW sensor
Check DHW sensor wiring
TANK ERR 3 sec
Tank sensor is shorted or has an open circuit. The control will
cease operation.
Check tank sensor
Check tank sensor wiring
POOL ERR 3 sec
Pool sensor is shorted or has an open circuit. The control will
cease operation.
Check pool sensor
Check pool sensor wiring
DEV LOST 3 sec
Device xx on heater bus is lost, if device is on the tN4 bus, the
zone is displayed as well.
Check wiring between VERSA IC
®
control board and all PIM™s on the net-
work
Check communication wiring for BMS system
DEV ERR 3 sec
More than 1 master detected on tN4 bus. tN4 device at dis-
played address (B:xx) has an error
Check DIP switches on cascaded heaters to make sure only 1 unit is set to
Master while the others are set to Followers/Slave. Check communication
wiring at heater with noted address
PIM™ 1 ERR 3 sec Communications with PIM™1 were established but then lost. Check cabling and DIP switch settings for Master/Follower configuration.
PIM™ 2 ERR 3 sec Communications with PIM™2 were established but then lost. Confirm cabling and DIP switch settings.
PIM™ 3 ERR 3 sec Communications with PIM™3 were established but then lost. Confirm cabling and DIP switch settings.
PIM™ 4 ERR 3 sec Communications with PIM™4 were established but then lost. Confirm cabling and DIP switch settings.
CONDENSATE 3 sec Condensate switch has tripped
Check for blockage of condensate drain
Check condensate switch
Check condensate switch wiring
Check for heat exchanger leak which might overwhelm the capacity of the
condensate drain causing this error
VENT TEMP 1 sec Vent temperature switch has tripped
Check vent temperature switch
Check vent temperature switch wiring
Check PVC/CPVC/Polypropylene vent for any damage due to excessive
temperatures
Check vent for leaks near vent temperature switch
AUTO LIMIT 3 sec Automatic high limit has tripped
Check the automatic high limit switch
Check the automatic high limit switch wiring
Check for proper pump operation
Check bypass (if equipped) for too much water flow
LOW WATER 1 sec Low water cut-off has tripped
Push reset button on LWCO control
Check LWCO probe & wiring
VENT BLOCK 3 sec Blocked vent switch has tripped
Check venting
Check vent pressure switch & wiring
Check vent pressure switch tubing
LOW GAS 1 sec Low gas pressure switch has tripped
Push reset button on low gas pressure switch Verify proper gas pressure
Open manual gas valves fully Clean out drip leg
HIGH GAS 1 sec High gas pressure switch has tripped Push reset button on high gas pressure switch Verify proper gas pressures
EXTRA 1 sec
Extra limit switch has tripped – see product I&O manual for
more detail if this limit is used and how to troubleshoot it.
See product specific I&O manual troubleshooting section
WATER FLOW 3 sec Water flow switch has tripped
Check heater pump operation Purge air from system Replace flow switch
as necessary
BLOWER 10 sec Blower air pressure switch has tripped Check air filter Check blower Check air pressure switch hose Check wiring
OPTION 1 10 sec
Factory option #1 switch has tripped. This switch uses a 10
sec delay on initial CFH before reporting the fault
Check wiring diagram to determine what is connected here
OPTION 2 30 sec
Factory option #2 switch has tripped. This switch uses a 30
sec delay on initial CFH before reporting the fault
Check wiring diagram to determine what is connected here
OPTION 3 90 sec
Factory option #3 switch has tripped. This switch uses a 90
sec delay on initial CFH before reporting the fault
Check wiring diagram to determine what is connected here Check field
interlocks such as combustion air damper proving switch
