Reset ratio the reset ratio setting determines how much the target temperature will increase as the outdoor temperature drops. The reset ratio is expressed in the following manner: x:y x - change in outdoor temperature y - change in target temperature the first number in the ratio refers to the chan...
Reset ratio chart 20 pump turn-off delay the pump turnoff delay works in conjunction with the outdoor cutoff temperature. The pump turnoff delay sets the delay between the time when the outdoor cutoff temperature is reached and the time when the pump is turned off. The pump turnoff delay is adjustab...
Boiler turn-on delay in a multiple boiler system: the boiler turn-on delay sets the time delay before each additional boiler is turned on in response to a call for heat. This delay starts when the preceding boiler is turned on. The boiler turn-on delay range is from 0 to 5 min. Recommended initial s...
