ON when relative humidity is equal to or greater than Parameter 188 setting.
OFF when relative humidity is less than Parameter 188 setting minus Parameter 191.
ON when relative humidity is within range.
Parameter 188 plus Parameter 191
Only ON when relative humidity is greater than Parameter 188. Otherwise service delay will be OFF.
When relative humidity falls below Parameter 188 the service delay is turned OFF once Parameter 193 setting (seconds)
is reached.
ON when indoor air quality/carbon dioxide is greater than Parameter 187 setting.
OFF when indoor air quality/carbon dioxide is less than Parameter 187 minus Parameter 190 setting.
ON when indoor air quality/CO2 within range.
Parameter 187 (SRV OUTPT SP CO2) plus Parameter 190 .
ON when indoor air quality/CO2 is greater than Parameter 187. Otherwise service delay will be OFF.
When indoor air quality/CO2 falls below Parameter 187 the service delay is turned OFF once Parameter 193 setting
(seconds) is reached.
ON when outdoor air temperature is greater Parameter 189 setting.
OFF when outdoor air temperature is less than Parameter 189 setting.
ON when outdoor air temperature is within range.
Parameter 189 plus Parameter 192.
ON when outdoor air temperature is greater than Parameter 189 setting. Otherwise service delay will be OFF.
When outdoor air temperature falls below Parameter 189 the service delay is turned off once Parameter 193 setting
(seconds) is reached.
