SYSTEM DIAGNOSTICS
The controller is equipped with diagnostic LED
lights that indicate the system status at any
particular time. The lights indicate the following
conditions:
HYDRONIC CIRCULATOR PUMP CONTROL
The hydronic circulator pump is energized either
GREEN = 24 Volt system power

internal pump relay (RP) and 3-pole terminal block
YELLOW = Fault or Lockout
(BP) or through an isolation relay having its 24Vac
RED = Anti-short-cycle mode
coil wired to the Y and X terminals.
If a set point controller installed with the heat pump
system has a lockout indicator, the controller will
send a signal from L on the terminal strip to a LED on
the thermostat to indicate a lockout condition.
REVERSING VALVE CONTROL
When 24Vac is applied to the O terminal on the
wiring block, the controller energizes its O output

or 3) high discharge refrigerant temperature. A
lockout condition means that the unit has shut itself
down to protect itself, and will not come back on
until power has been disconnected (via the circuit
breaker) to the heat pump for one minute.
Problems that could cause a lockout situation
include:

connector.

Hydronic Heat Pump – Supplying Radiant Floor Heating, Fan Coil Cooling, and Water Heating
Note – Always use copper pipe on the hydronic side.
Note – Conceptual drawing only. Check local codes and use proper plumbing procedures.
Important – Expect a 10°F temperature differential between supply tank and receiving tank when transferring heat with an intermediate heat
exchanger.

Ground Loop Plumbing
FNote – These units feature braze-plate heat exchangers. Enertech requires that a strainer be installed on the water inlet of the source circuit. A
strainer with a size of 16-20 mesh minimum should be used. For your convenience a strainer and connection hardware have been included with
the unit.

CHECKS AND CORRECTIONS
POSSIBLE CAUSE
Blown Fuse/Tripped Breaker
Replace fuse or reset circuit breaker (check for correct size).
Blown Fuse on Controller
Replace fuse on controller. Check for correct size fuse or loose fuse clips.
Broken or Loose Wires
Replace or tighten the wires.
Entire unit Voltage Supply Low
does not run.
Low Voltage Circuit
If voltage is below minimum voltage on data plate, contact power company.
Check 24-volt transformer for burnout, blown fuse or voltage less than 18 volts.
Remote Hydronic Control or
Room Thermostat
Set system to "Cool" and lowest temperature setting, unit should run. Set system to
"Heat" and highest temperature setting, unit should run. If unit does not run in either
case, the hydronic control (or room thermostat) could be faulty or incorrectly wired.
To check, disconnect thermostat wires at the unit and jumper between "R", "Y" and
"G" terminals, and unit should run. Only replace with correct replacement. A
substitute may not work properly.
Interruptible Power
Check incoming supply voltage.
Water
Lack of sufficient pressure, flow, temperature and/or quantity of water.
Unit Undersized
Recalculate heat gains or losses for space to be conditioned. If excessive, rectify by
adding insulation, shading, etc.
Loss of Conditioned Air by
Leaks
Check for leaks in ductwork or introduction of ambient air through doors and
windows.
Thermostat
Improperly located thermostat (e.g. near kitchen inaccurately sensing comfort level in
living areas). If thermostat has an anticipator, set at 1.0 or 1.2.

CHECKS AND CORRECTIONS
POSSIBLE CAUSE
Airflow (Across fan coil)
Lack of adequate airflow or improper distribution of air. Check the motor speed and
duct sizing. Check the filter, it should be inspected every month and changed if dirty.
Remove or add resistance accordingly.
Refrigerant Charge
Low on refrigerant charge causing inefficient operation. Adjust only after checking
CFM, GPM and inlet/outlet temperatures.
Compressor
Check for defective compressor. If discharge pressure is too low and suction pressure
too high, compressor is not pumping properly. Replace compressor.
Reversing Valve
Defective reversing valve creating bypass of refrigerant from discharge to suction
side of compressor. When necessary to replace reversing valve, wrap with wet cloth
& direct heat away. Excessive heat can damage the valve.
Desuperheater
The desuperheater circuit (in-line fuse) should be disconnected during cold weather
to allow full heating load to house.
Remote Hydronic Control or
Room Thermostat
Check setting and wiring. If thermostat has an anticipator, set it at 1.0 or 1.2.
Wiring
Check for loose or broken wires at compressor, capacitor, or contactor.
Blown Fuse
Replace fuse or reset circuit breaker (check for correct size).
The unit could be off on high pressure, low-pressure or discharge refrigerant

wiring. Replace if defective.
Defective Capacitor
Check capacitor, if defective remove, replace, and rewire correctly.
Voltage Supply Low
If voltage is below minimum voltage specified on the data plate, contact local power
company. Check voltage at compressor for possible open terminal.
Low Voltage Circuit
Check 24-volt transformer for burn out or voltage less that 18 volts. With a voltmeter,
check signal from thermostat at Y to X, M1 on controller to X, capacitor voltage drop.
Replace component that does not energize.
Compressor Overload Open
In all cases an "internal" compressor overload is used. If the compressor motor is too hot,
the overload will not reset until the compressor cools down. If the compressor is cool and
the overload does not reset, there may be a defective or open overload. Replace the
compressor.
Compressor Motor Shorted to
Ground
Internal winding grounded to the compressor shell. Replace the compressor. If compressor
burnout replace the liquid line filter/drier.
Compressor Windings Open
Check continuity of the compressor windings with an ohmmeter. If the windings are open,
replace the compressor.
Seized Compressor
Try an auxiliary capacitor in parallel with the run capacitor momentarily. If the
compressor still does not start, replace it.
Remote Hydronic Control or
Room Thermostat
Improperly located thermostat (e.g. near kitchen, inaccurately sensing comfort level in
living areas). If thermostat has an anticipator, set at 1.0 or 1.2.
Compressor Overload
Defective compressor overload, check and replace if necessary. If the compressor runs too
hot, it may be due to insufficient refrigerant charge.
Aquastat
The differential is set to close on Aquastat. Increase differential setting to 15oF.
Wiring and Controls
Loose wiring connections, or control contactor defective.
Thermostat Improperly Set
Is it below room temperature? Check the thermostat setting.
Defective Thermostat
Check thermostat operation. Replace if found defective.
Unit will not Incorrect Wiring
operate in
“heating” Aquastat set Too High
Check for broken, loose, or incorrect wires.
Heat pump is trying to heat hot water to too hot of a temperature (over 120oF). Reduce
Aquastat set point.

PROBLEM
Remote Hydronic Control or
Room Thermostat
Ensure that these products are properly configured according to their own instructions for
the “System Type” they are installed on.
Reversing Valve does not Shift
Defective solenoid valve will not energize. Replace solenoid coil.
Reversing Valve does not Shift,
the Valve is Stuck
The solenoid valve is de-energized due to miswiring at the unit or remote control correct wiring. Replace if valve is tight or frozen and will not move. Switch from heating to
cooling a few times to loosen valve.
Unit does not

Aquastat set Too Low
(Heats Only)
Insufficient Antifreeze
Noisy
Operation
CHECKS AND CORRECTIONS
POSSIBLE CAUSE
Heat pump is trying to cool water too low. Increase Aquastat set point.
Water is freezing in hydronic coil. Check antifreeze level and add antifreeze to obtain
correct freeze protection.
Compressor
Make sure compressor is not in direct contact with base or sides of the cabinet. Cold
surroundings can cause liquid slugging, increase ambient temp.
Contactor
A "clattering" or "humming" noise in the contactor could be due to control voltage less
than 18 volts. Check for low supply voltage, low transformer output or extra long runs of
thermostat wires. If the contactor contacts are pitted or corroded or coil is defective, repair
or replace.
Rattles and Vibrations
Check for loose screws, panels, or internal components. Tighten and secure. Copper
piping could be hitting the metal surfaces. Carefully readjust by bending slightly. Ensu
hard plumbing is isolated from building structures.
Water and Airborne Noises
Excessive water through the water-cooled heat exchanger will cause a squealing sound.
Check the water flow ensuring adequate flow for good operation but eliminating the noise.
Cavitating Pumps
Purge air from ground loop or hydronic loop system.
Squealing Sound from Inside the
Cabinet
Purge air from the water side of the desuperheater heat exchanger or defective
desuperheater heat exchanger.
