D. The Delay function is for the Blower-Off delay during cooling only. Once the thermostat has satisfied the call
for cooling, the blower will continue to run at 82% of the selected speed for the delay period. The selections are
follows:

There is a predefined Blower-On ramp function for cooling only. Upon the thermostat call for cooling, the
blower will run at 50% for 30 sec. after which it will run at 82% for the next 30 sec. Then the blower will run at
100% of the selected cooling speed until the thermostat is satisfied.
E. The optional blower delay jumpers on the integrated control (Figure 14) are used to determine the length of the
heat delay–to-fan-off periods. The delay-to-fan-on period is preset and non-adjustable. The available options for
the delay-to-fan-off are as follows: 60, 90, 120 & 180 sec.
6. Field Wiring and Replacement Wiring
Field wiring between the furnace and devices not attached to the furnace shall conform with the temperature
limitation for Type T wire [63°F rise (35°C)] when installed with the manufacturer's instructions. If any of the
original factory supplied furnace wiring is replaced, or a separate device other than the thermostat is wired internal to
the unit, 105°C thermoplastic or equivalent wire must be used.

M. ADDITIONAL FEATURES

1. Heat Staging
The CLHX1 furnace control board has the option of selecting the preferred method for the activation of the second
stage of heating. Selections are made with a jumper at the P5 terminal strip (see Figure 14). The selections available
are as follows: OFF, 10, 15 & 20. The default selection is OFF.
Selecting 10, 15 or 20 will enable the furnace to activate second stage heating once it has run for 10, 15 or 20
minutes at the low stage. Selecting the OFF position will require that the furnace received a call for W2 heat from the
thermostat to enable the second stage of heating.
2. Thermostat Call for Fan
When the thermostat calls for continuous fan (G) without a call for heat or cooling, the indoor fan is immediately
energized according to the jumper setting on P17 (see Figure 14). The jumper selection offers 5 speeds for
continuous fan (VS G, High Cool, Low Cool, High Heat and Low Heat). VS G indicates that the control should use
the pre-programmed Variable Speed for G, which is 50% of the selected High Cool speed.
3. Dehumidifier (Dehum) and Heat Pump
The CLHX1 furnace control board has jumpers which should be used to indicate the presence of a dehumidifier, or
operation with a heat pump. A jumper is provided for each option, and available selections are marked YES and NO.
