About this file
This document is a furnace product data sheet for a heating and cooling system specification associated with the Minnesota Department of Natural Resources' Mystery Cave Visitor Center Furnace Replacements project (RFB 2027-433). The sheet provides comprehensive technical specifications for a two-stage furnace system with integrated furnace control (IFC), detailing electrical ratings, wiring configurations, operational timings, and performance parameters. The furnace is designed for multi-stage heating and cooling operation with heat pump capability, featuring a 24 VAC input at 60 Hz with 450 mA transformer secondary current and various output specifications including blower motor, igniter, and inducer outputs. The document includes detailed wiring diagrams, terminal designations, and field wiring instructions for both standard and heat pump configurations, as well as condensate switch options.
The technical specifications outline default blower motor tap selections for different operational modes (continuous fan, cooling stages, heating stages, and heat pump operation), error codes with corresponding diagnostic meanings, and operational status indicators displayed on a seven-segment display. Key operational timings include prepurge at 0 seconds, interpurge at 60 seconds, post purge at 5 seconds, ignition warmup at 20 seconds, and a heat-on delay of 30 seconds. The documentation includes extensive notes addressing wire temperature ratings, pressure switch configurations, thermostat jumper requirements, airflow adjustments, flame sense test procedures, and model-dependent variations. Acceptable flame current range is specified at 0.75 to 3 microamps, with flame sense test pads rated at 1 VDC per microamp. The sheet serves as the product data specification that bidders must comply with when furnishing four new furnaces for the visitor center replacement project.

NOTES:
1. IF ANY OF THE ORIGINAL WIRING AS SUPPLIED WITH THIS FURNACE MUST BE REPLACED, IT MUST BE WITH WIRE HAVING A TEMPERATURE RATING OF AT LEAST 105°C. WIRES 12, 18, 48, 49, 50, AND 51 REQUIRE A TEMPERATURE RATING OF AT LEAST 250° C.
2. FOR PROPER AIRFLOW IN COOLING/HEAT PUMP MODES, Y1 AND/OR Y2 MUST CONNECT FROM THE THERMOSTAT TO THE IFC LOW VOLTAGE TERMINAL STRIP.
3. FOR COOLING ONLY SYSTEMS, LEAVE Y1-O JUMPER IN PLACE ON THE IFC FOR CORRECT LED READOUT.
4. FOR HEAT PUMP SYSTEMS, REMOVE THE Y1-O JUMPER, CONNECT "O" FROM THE THERMOSTAT TO "O" ON THE IFC LOW VOLTAGE TERMINAL STRIP
FOR CORRECT LED READOUT AND DEFROST OPERATION.
5. IF USING A SINGLE STAGE HEATING THERMOSTAT, JUMPER W1 AND W2 TERMINALS AT THE LOW VOLTAGE TERMINAL STRIP. HT2 WILL BE SHOWN ON THE SEVEN SEGMENT DISPLAY AT ALL TIMES. SECOND STAGE OPERATION WILL BEGIN AFTER THE INTERSTAGE DELAY HAS COMPLETED.
6. TO CHANGE AIRFLOW, REFER TO THE INTEGRATED FURNACE CONTROL MENU AND OPTIONS TO SET AIRFLOW AND BLOWER DELAYS.
7. WIRE YL/45 AND RAF-2 ARE NOT PRESENT ON DOWNFLOW MODELS.
8. FLAME SENSE TEST PADS: 1 VDC = 1 MICROAMP. FLAME CURRENT CAN VARY DEPENDING ON THE VOM THAT IS USED AND THE VOLTAGE SUPPLIED TO THE FURNACE. THE ACCEPTABLE RANGE IS 0.75-3 MICROAMPS.
9. IF APPLICABLE CONNECTION FOR FACTORY PROGRAMMING ONLY.

Notes:
1) HP = Wiring used for Heat Pump System.
2) CS = wiring used for Condensate Switch (2 Options).
3) Y1 and/or Y2 must be connected from the thermostat to the IFC for proper airflow.
4) Remove Y1-O jumper for HP systems. O terminal must be connected as shown for gas heating operation during defrost.
5) If the thermostat does not have a W2, or there are not enough conductors, jumper W1 to W2 at the IFC.
6) A/TCONT824 thermostats do not require the use of X2.
7) Recommended 1 st stage airflow is 75% of total airflow.
