CBX02003

The CBX02003 sheet is a fan blower post-purge time delay. Features listed are a dual function of 7 second on delay and 65 second off delay, speed-up terminals for test mode, fuse-protected control voltage, and a high-power relay output. On a call at the G terminal, a 7 second delay on make begins, then the control energizes the blower. When G is removed, the blower stays on for 65 seconds and then shuts off.

Specifications list a control voltage of 18 to 30 Vac at 50/60 Hz. The output is an SPST normally open relay rated 25 amps at 240 Vac. Time delays are 7 seconds on and 65 seconds off. Environment is -20 F to 200 F and 5 to 95 percent non-condensing. Speed-up options are speed-up to C for a reduced delay of 3 seconds on and 5 seconds off, and speed-up to R for no delay. The sheet says the control replaces Goodman PCBFM 103. This page already states the 65 second post-purge time.
