I have a 2015 Fun Finder 266 KIRB with a 13.5K BTU 579 Series Dometic Brisk 2 A/C.
The reason I am asking is I am installing a Progressive Industries EMS-HW50C (yes, the trailer is wired for 50 Amp) and I need to know how to set the delay jumper on the unit. 15 seconds or 136 seconds?
Your Brisk II does not have any delay so you want to set your Progressive EMS for a 136" delay by removing the internal jumper. I went one step further and wired an SPST switch across the jumper contacts so I can instantly switch delay between 15" for those times in cooler weather when we're not using A/C and 136" in hot weather when we are.
Pics are in my gallery starting here. :)
Why do you state there is NO delay? The AC has NO controls. It is controlled by the Wall Tstat and ITS upper control board, which DOES have a delay. The delay is usually 2 minutes 45 seconds, but can vary. IF you have a Power Outage, it will restart the delay timer. That is to keep from overloading the 20 amp breaker or the overload on the compressor. The delay gives the compressor time to lose(equalize) its head pressure. IF you have Roof top mechanical controls, then there is NO delay. Doug
From the Dometic manual for electronic controls
Compressor Time Delay
A time delay of approximately two minutes occurs any time the compressor is required
to begin the cooling or heat pump cycle.
