Error
Code Error Name Error Description
Error
Type
Cause
Solution
A4A2 Red Hose
Overcurrent
An over current was detected
on the output
Alarm
Bad heaters
Measure resistance of heater
A4A3 Red Inline
Overcurrent
A4A6 Red Blanket
Overcurrent
A4A7 Red Chiller
Overcurrent
High voltage
Measure voltage across the disconnect switch.
Voltage should measure between 190 and 264 Vac.
A4B1 Blue Inline
Overcurrent
Bad heaters
Measure resistance of heater
A4B4 Blue Hose
Overcurrent
A4B5 Blue Blanket
Overcurrent
A4B8 Blue Chiller
Overcurrent
Shorted Temperature
Control Module
If temperature rises for a zone that has been
disabled, replace Temperature Control Module
A4H1 Motor Over
Current
High current has been
detected on a phase and has
been shutdown to prevent
damage
Bad internal wiring of the
motor
Replace motor
Short circuit of motor
wiring
Check wiring to the motor to ensure no bare wires are
touching and that no wires are shorted to ground
A4H3
Mix Head
Motor
Overload
Excessive Current to AC
Power Pack Motor.
Short circuit within AC
Power Pack Motor.
Replace motor.
A4M1 Motor Over
Current
Too much current is being
drawn from the wall
Low voltage from the
wall during load
Make sure the supply line is properly sized for the
load and is above the minimum voltage requirements
A4N1 Motor Over
Current
A hardware current fault has
occurred causing a system
shutdown
Short circuit of motor
wiring
Check wiring to the motor to ensure no bare wires are
touching and that no wires are shorted to ground
Motor rotor has become
locked
Unplug the directional valve (so pressure will not
build) and try to move the motor again. If this
succeeds then the power pack may need to be
replaced. If the motor is still unable to move, the
bearings or hydraulic pump have likely failed in the
motor and will need to be replaced.
A7A2 Red Hose
Control Fault
Unexpected current to
heater/chiller
Shorted Temperature
Control Module
If temperature rises for a zone that has been
disabled, replace Temperature Control Module
A7A3 Red Inline
Control Fault
A7A6 Red Blanket
Control Fault
A7A7 Red Chiller
Control Fault
A7B5 Blue Blanket
Control Fault
A7B1 Blue Inline
Control Fault
A7B4 Blue Hose
Control Fault
