Additional Features
General
• Eliminates the need for air temp thermostat to control fan cycling by using time instead.
• Selectable blower turn-on and turn-off delays to adjust comfort & efficiency
(turn-on: 30, 60, 120 & 240 sec; turn off: 2, 4, 6 & 8 min)
• Three blower operating choices: HEAT, COOL & FAN for best efficiency for each mode.
• Reduces A/C blower speed 50% on demand to increase dehumidification.
• Cooling blower delays of 10 seconds on, and 45 seconds off to enhance cooling comfort and efficiency.
Cycle Control
• 4 minute minimum A/C off time to reduce Short-Cycle related failures.
• A high limit will cause the blower run at the selected HEAT speed. It will then run for the HEAT turn off
time afterwards in the absence of a HEAT call.
• Blower operation will "time out" before mode is switched between HEAT & COOL to prevent stress related
evaporator failures.
• Burner Cut-Off on high limit
Speed Control
• Selectable air temperature (heat) rise from Return to Supply Plenum (choose from: 63, 69, 75 and 85 º F)
• Selectable CFM rates for matching A/C tonnages. These CFM selections support from 2.0 to 3.5 tons.
• Maximum CFM's are limited by the maximum RPM of the ECM motor and the duct static pressure.
Please refer to the manual addendum for guidelines.
Diagnostics
• Control Input LED's indicate active thermostat input lines.
• Diagnostic LED indicate:
1. Active Operation (turn full on during burner or compressor operation)
2. A HIGH LIMIT condition. (flash on/off at 2 ½ times per second)
