thermostats will need 250 ohm, 10 watt
resistors on each of the W and Y
terminals.
Heat Anticipator Setting
For optimum comfort the anticipator
setting should be set to provide
approximately 4 cycles per hour
Typical Heat
Anticipator Setting
0.25 amps
Thermostat wire from the thermostat is
connected to the wires located inside the
air handler. The thermostat should be
connected as follows:
R – power (red) (24vac)
W – heating (white)
Y– cooling (if present) (yellow)
G – continuous run fan (if present on
thermostat) (black or brown)
Boiler
If the optional fourth relay is installed, the
yellow wires labeled TT on the relay are
dry contacts for connection to a boiler or
external pump. A relay for the boiler may
be field installed. The relay shall be
24VAC, SPST-NO and the coil
connected to W and ground.
A/C Condensing Unit
Connect to Y (yellow) and C (green).
Pump Exerciser
An optional pump exerciser with fourth
relay may be ordered factory installed or
may be field installed. Connect to R
(red), W (white) and C (green). It will
operate the pump once a day for 30
seconds. NOTE: It’s first on-cycle will be
as soon as power is applied to the air
handler.
START-UP PROCEDURES
Do not start the air handler or water
heater until ALL air has been purged!
1.Fill the boiler loop or water heater with
water, but do not start it.
2.Purge all air from the boiler heating or
domestic water system.
3.Purge all air from the space-heating
loop by closing the isolation valve on the
return leg of the loop and open the drain
to purge air. Open the return leg isolation
valve and then close the drain valve.
4.Start the boiler or water heater
according to the manufacturer’s
instructions. Set the design water
temperature and wait for the system to
shut off. You can check that the water
heater is set properly by running hot
water from a faucet into a glass. Using a
thermometer measure the temperature of
the water as soon as the water heater
burner shuts off. If the set-point
temperature is too low or is above 140F,
reset the tank control, run water until the
burner starts again and repeat the
measurement.
5.Turn on the power to the air handler
and set the room thermostat for heat to
energize the fan and pump. If a gurgling
sound is present, it should subside within
