Connecting Thermostat

Compatible with most 24V thermostats. Standard 5-wire connection.

Turn off power to furnace at main disconnect.
Remove thermostat subbase and connect wires according to diagram.
Match wires to terminals (R, W, Y, G, C).
Secure connections and replace subbase.
Restore power and test thermostat operation.

Tip: Use compatible thermostat for optimal performance and efficiency.

Operation

Heating cycle controlled by thermostat and control board.

Thermostat call: Thermostat signals for heat when temperature drops below set point.
Blower start: Indoor blower starts to establish airflow.
Element activation: Heating elements energize in sequence based on demand.
Temperature rise: Air heated as it passes over heating elements.
Cycle completion: System shuts off when thermostat set point reached.
Blower run-on: Blower continues to run briefly to dissipate residual heat.

WARNING! Do not block vents or returns. Maintain clear airflow paths.

Maintenance Procedures

Regular maintenance ensures optimal performance and longevity.

Monthly: Check and replace air filter as needed.
Seasonal: Inspect heating elements and electrical connections.
Annual: Professional inspection and cleaning recommended.
Blower maintenance: Clean blower assembly and check motor operation.
Safety check: Test limit switches and safety controls.

CAUTION! Disconnect power before performing any maintenance. Use qualified technician for electrical components.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No heat	Power supply, thermostat, limit switch	Check circuit breaker; verify thermostat settings; reset limit switch.
Insufficient heat	Dirty filter, airflow restriction	Replace air filter; check for blocked vents or returns.
Blower not working	Motor, capacitor, control board	Check motor operation; test capacitor; inspect control board.
Frequent cycling	Thermostat location, dirty filter	Relocate thermostat away from heat sources; clean/replace filter.
Strange noises	Loose components, motor issues	Tighten all fasteners; inspect blower motor and wheel.
Diagnostic light flashing	System fault detected	Count flashes and refer to diagnostic code chart in manual.

Reset: Turn power off for 30 seconds, then restore to reset control board.
