STEP 6: TEMPERATURE COMPENSATION
Thedeviceincludesanoutdoortemperaturecompensaonfunconthatcan
beenabledfromthemenu.Whenacvatedandanoutdoortemperaturesensor
isaached,theeecvesetpointofthedevicewillbemodiedtocompensate
forthecoldoutdoorair.Thismayresultinenergysavings.
If temperaturecompensaonis enabled, thedevicewill linearly decreasethe
user’s setpoint (REF FLOW/REF PRESSURE) by 0 % to TC DROP % from TC
START TE to TC STOP TE.
Thedeviceenforcesa+5°Cdierence betweenthe startand stoptempera-
tures.Thestarttemperaturemustbehigherthanthestoptemperature.
