Hydrolevel OFC-5023 Oil Furnace Fan Timer Control for 2 or 3 Speed PSC Motors

The Hydrolevel OFC-5023 (part number 47-50231) is an oil furnace fan timer control, also called a furnace blower timer board. It works with 2- or 3-speed PSC (permanent split capacitor) blower motors, so one control can serve many oil furnace setups.

Key Features:

• DIP switches match the control to 2- or 3-speed motors and set the blower ON and OFF delays, so no programming tools are needed
• Field-adjustable blower ON/OFF delay and counter flow settings
• Blower outputs for Cool, Heat, Low and continuous fan
• Dehumidifier (Dh) terminal coordinates fan operation with dehumidification calls
• Status LEDs for thermostat calls at W, Y, G and Dh, plus BURNER ON, BLOWER ON, LIMIT OPEN and SYS OK indicators for faster troubleshooting
• Industry-standard wiring terminals and relays

The control suits oil furnace retrofits where you want quick change-outs with minimal wiring changes and adjustable blower timing.
