Description
The 1 speed fan control board (R60B) is an electronic fan control board which provides, in one device, control of a line voltage fan motor. The primary purpose is to control the fan motor use in air-conditioning & heating systems. The control board is powered by 24VAC input and will accept a 24VAC fan signal from the thermostat.
Features
The control board has a fixed 1 second fan ON delay. There is a fixed 45 seconds post fan OFF delay in which the relay will be energized for another 45 seconds after the thermostat fan signal (G) is turned off. Screw-in terminals will be use for R, C and G connections. Fan connections will be quick connects located on the relay. The board and its 24VAC output to the thermostat are protected by an in-line 3 Amp blade type replaceable fuse.
