sensor and the default curve does not work for your region.

+10C1
32º F - 248º F Default 86º F
Supply water temperature at 50º F (+10º C) outside temperature
The sample reset schedule shown in the chart is the default. To set +10C1 (50º F) & -10C1 (14º F) select the
water temperature you want at those outside temperature on the vertical F scale.
Suggested Initial Settings
Leave +10C1 at 86º. At 50ºF outside the supply temperature will be 86º F.
Set -10C1 so that at the outside design temperature in your area the supply temperature will be near the maxi-
mum temperature allowed in your system.
