SECTION III: OWNERS INFORMATION
AND SEASONAL INFORMATION
How The Furnace Works
This furnace may be installed in the downflow or the
horizontal position. Figure 1 shows a typical model in the
downflow position. The furnace is equipped with a relay,
sequencer, transformer, circuit breakers, and a blower
assembly. The transformer provides 24 VAC to the
thermostat. When the thermostat calls for heat the relay(s)
energize sending 240 VAC to the electric heaters causing them
to get hot. The indoor fan motor is then energized on the low
speed tap and the circulating blower draws cool air from the
living space, passes it across the heater coils and circulates the
warmed air through the duct work to the house. When the
blower stops the heating cycle has ended and the furnace is
ready for the next call for heat to start the next cycle.
The furnace is equipped with the controls necessary for proper
and safe operation. The various components referred to in this
manual are identified in Figure 1.
Figure 1: Component Locations
Examination of the Furnace
The homeowner should perform a visual examination of the
furnace every month for any defects or problems. The items to
be inspected are:
1. The physical support of the furnace is sound without
sagging cracks, gaps, etc. around the base so as to
provide a seal between the support and the base.
2. The furnace casing for any obvious signs of
deterioration from rust or corrosion.
3. The return and supply duct connections are
physically sound and are sealed to the furnace casing.
4. The furnace must be serviced by qualified personnel
annually, preferably at the start of each heating
season.
The Service Technician
The furnace’s best friend is a qualified service technician. If
the unit gives any indication of improper operation, call the
service technician. The service technician is allowed to
perform the normal routine care of your furnace. He can detect
potential problems and make corrections before trouble
develops. Preventative maintenance of this type will allow the
furnace to operate with minimal concerns to the homeowner
and will add years of comfort.
Warranty and Responsibilities
It is the sole responsibility of the home owner to make certain
the furnace has been properly installed and adjusted to operate
properly.
The manufacturer warrants the furnace to be free from defects
in material or workmanship for a stated time in the warranty
agreement. The manufacturer will not be responsible for any
repair costs to correct problems due to improper setup,
improper installation, improper furnace adjustments, adding
parts that are not listed for use with this furnace, improper
operating procedures by the user.
Some specific examples of service calls which will be
excluded from warranty reimbursement are:
1. Correcting faulty duct work in the home. This can be
due to not enough ducts or ducts are too small to
provide proper air flow through the furnace.
2. Correcting wiring problems in the electrical circuit to
the furnace.
FIRE OR ELECTRICAL HAZARD
Servicing heating/cooling equipment can be hazardous due
to electrical components.
Only trained and qualified personnel can service or repair
heating/cooling equipment. The home owner must never try
to perform service, repair or maintenance on this appliance.
Untrained service personnel can perform only basic
maintenance functions such as cleaning of exterior
surfaces and replacing the air filters.

has a limit control directly in front of it to sense
overheating of the element and open if the
temperature gets above the set point of the limit
control.
2. The Heater Relays – The electric heater relays
simply turn the heater elements on and off. The
relays are controlled by the thermostat. On a call for
heat 24 VAC is sent to the relay(s) 24 VAC coil
energizing the relay. When the call for heat has been
satisfied the 24 VAC is removed from the relays 24
VAC coil de-energizing the relay(s).
3. Cooling Sequencer – The cooling sequencer is used
only when 24 VAC is on the “G” terminal from the
thermostat. The sequencer controls the blower 28 sec
on and 14 sec off time delay.
4. Circuit breakers – The circuit breakers are designed
as over-current protection for the electric heaters
only. The circuit breakers MUST NEVER be used for
over-current protection for the transformer, 24 VAC
circuit, or the blower motor.
5. 3 Amp Fuse – This fuse is used for over-current
protection of the 24 VAC circuit.
6. Transformer – The transformer is used to step down
voltage from 240 VAC to 24 VAC. The transformer
provides the required 24 VAC for the system control
circuit.
7. PSC Motor Isolation Relay - This relay is used for
the PSC motor. This relay is used as an isolation
relay to isolate the cooling speed tap from the heating
speed tap on the PSC motor. The wiring has been
designed so that the normally closed contacts are
used for heating and the normally open contacts are
used for cooling. The relay coil is energized with a
call from the “G” terminal on the thermostat.
8. PSC motor Time Delay Sequencer - The heating
sequencer is used only when 24 VAC is on the “G”
terminal from the thermostat. The sequencer controls
the blower 28 sec on and 14 sec off time delay.

The thermostat has a manual switch that can be moved to the
“On” position or it can be programmed for continuous fan
operation. This setting causes the thermostat to complete the
circuit between “R” and “G” terminals on the thermostat
causing the sequencer to energize starting the blower motor
delay on. When the sequencer has completed the delay on
cycle the contacts will close sending 24 VAC to the selected
indoor blower motor speed tap.
This will cause the indoor blower to operate continuously until
the 24 VAC signal has been removed by changing the fan
operation from continuous to auto.
Intermittent Blower - Cooling
The thermostat has a manual switch that can be moved to the
“Auto” position or it can be programmed for auto fan
operation. When the thermostat calls for cooling, a circuit is
completed between the “R, “Y” and “G” Terminals. The
indoor fan motor is energized from the “G” terminal on the
thermostat through the sequencer to the motor and the motor
will operate on the speed tap that has been selected for “G”.
The sequencer “ON” delay for the indoor fan motor is 28 sec
and the “Off” delay is 14 sec.
The Heating Cycle
When the thermostat is in the HEAT mode, the fan is set to
AUTO.
When the thermostat calls for heat (X-13 Blower Motor)
1. The thermostat closes the circuit between the “R” and
“W” terminals.
2. 24 VAC is sent from the “W” terminal, through the
white thermostat wire to the white pigtail wire on the
furnace.
3. 24 VAC is sent from the W2 terminal through the
black thermostat wire to the white pigtail wire on the
furnace. Used on the 15 kW, 17 kW and 20 kW
models only.
4. 24 VAC is sent through the white pigtail wire to the
24 VAC coil on the heater relay(s).
5. This signal energizes the heater relays closing the
contacts to the heaters.
6. 240 VAC is sent from the relay contacts through the
limit switch(s) to the heater element(s).
7. At the same time, 24 VAC is sent from 24 VAC
heater relay coil through a white wire connected to
the low speed tap on the blower motor. The indoor
fan motor is energized on low speed after a 5 sec on
delay.
When the thermostat call for heat has been satisfied
1. The thermostat opens the circuit between the “R” and
“W” terminals.
2. 24 VAC is removed from the “W” terminal on the
thermostat and the white thermostat wire that is
connected to the furnace pigtail wire.
3. The thermostat opens the circuit between the “R” and
“W2” terminals.
4. 24 VAC is removed from the “W2” terminal on the
thermostat and the black thermostat wire that is
connected to the furnace pigtail wire.
5. 24 VAC is removed from the white pigtail wire and
the 24 VAC coil on the heater relay(s)
WINCHESTERHamiltonHomeProductsPage11
6. This de-energizes the heater relays opening the
contacts to the heaters.
7. 240 VAC is removed from the relay contacts, the
limit switch(s) and the heater element(s).
8. At the same time, the 24 VAC is removed from the
low speed tap on the blower motor. The indoor fan
motor low speed tap is de-energized after a 5 sec off
delay.
The heating cycle is complete, and the furnace is ready for the
start of the next heating cycle.
The Cooling Cycle
When the thermostat calls for cooling
1. The thermostat closes the circuit between the “R”, “Y
and “G”” terminals.
2. 24 VAC is sent from the “Y” terminal through the
Yellow thermostat wire to the 24 VAC coil terminal
on the condenser contactor.
3. At the same time the “Y” terminal has 24 VAC
placed on it, the “G” terminal is sending 24 VAC
through the green pigtail wire to the 24 VAC coil
terminal on the indoor blower sequencer.
4. The sequencer goes through a 28 second on delay,
and then closes the contacts sending 24 VAC to the
black wire connected to the selected indoor fan motor
speed tap.
5. The 24 VAC signal on the “Y” terminal energizes the
compressor contactor closing the contacts and
sending 240 VAC to the compressor and the outdoor
fan motor.
When the thermostat call for cooling has been satisfied
1. The thermostat opens the circuit between the “R”, “Y
and “G”” terminals.
2. 24 VAC is removed from the thermostat “Y”
terminal, the Yellow thermostat wire and the 24 VAC
coil terminal on the condenser contactor.
3. At the same time the “Y” terminal has 24 VAC
removed, the “G” terminal is removing 24 VAC from
the green pigtail wire and the 24 VAC coil terminal
on the indoor blower sequencer.
4. The sequencer goes through a 14 second off delay,
and then opens the contacts removing 24 VAC to the
black wire connected to the selected indoor fan motor
speed tap.
5. The 24 VAC signal on the “Y” terminal de-energizes
the compressor contactor opening the contacts and
removing 240 VAC from the compressor and the
outdoor fan motor
The cooling cycle is complete, and the cooling unit is ready
for the start of the next cooling cycle.
The PSC Motor Isolation Relay
This relay is used in conjunction with the motors to prevent
the possibility of the motors being energized on two speed
taps at the same time. This condition would burn out the motor
windings.
A black wire is connected from the circuit breaker to the
supply side of the normally open (N/O) terminals on the relay.
The blower motor high speed tap wire is connected to the load
side normally open terminal on relay.
A red wire is connected from the heat relay to the normally
closed (N/C) terminal on the relay. The load side of the
normally closed terminal is connected to the low speed tap
blower motor.

Section V: TROUBLESHOOTING
The following checks should be made before troubleshooting
the furnace controls for a no heat issue.
1. Check all of the circuit breakers. Make sure they are
turned to the “ON” position and have not tripped.
2. Check all fuses, especially the 3 amp fuse on the right
side of the control box. If the fuse is blown, check the
wiring with an OHM meter for a short to ground.
Repair the short, and then replace the fuse.
3. Check any switches that are external to the furnace to
make sure they are turned on.
4. Make sure all wiring connections, especially on any
of the components, to ensure they are securely
fastened.
If you have 240 VAC coming out of the circuit breakers in the
control box and you have 24 VAC between the load side if the
3 amp fuse and ground, then continue on through the rest of
the checks.
5. Remove the furnace door. Place your hand near the
blower motor. If you feel any heat rising up from the
blower wheel but the motor is not running, check for
240 VAC and 24 VAC at the motor terminals. If the
For personal safety be sure to turn the electrical power
“OFF” at the main entrance (Circuit Breaker Box) and at the
control box circuit breakers before attempting any service or
maintenance operations. Homeowners should never attempt
to perform any maintenance which requires opening the
furnace control box door.

240 VAC and 24 VAC is present at the motor
terminals but the motor is not operating, then replace
the motor. Refer to Figure 12 and Table 1 for
terminal locations and definitions.
6. If 240 VAC is not present at the motor check for a
broken wire between the circuit breakers and the
motor. If 240 VAC is present at the motor terminals
continue to the next check.
7. If 24 VAC is not present at the motor check for 24
VAC across the heater relay coil. If 24 VAC is
present at the heater relay coil then, the wire going to
the motor is bad and needs to be replaced.

10. Check for 240 VAC between each of the heater
elements. If 240 VAC is present, check the current
draw on each heater. If a heater is not drawing the
proper current or is showing almost no current draw
then, replace that heater.
The heater amps are as follows:
4 kW Heater = 16.7 amps
5 kW Heater = 20.8 amps
6 kW Heater = 25.0 amps
11. If 240 VAC is not present at the heater element but
there is 240 VAC present between the load terminal
of the relay and L2 then check the limit control for an
open limit and replace the open limit control.
12. If 240 VAC is not present at the heater element or
between the load terminal of the relay and L2 then
replace the heater relay.
