Settings and Calibration
The T104F Control includes an adjustable range limit-
ing pin (order additional pins separately). The pin is fac-
tory-set to limit the low range of the control to the frost
protection (*) setting (see Fig. 5). The pin can be moved to
a different low or high limit setting and lock point, or it can
be removed. Use a second pin if both low and high limit
settings are desired.
Setting the Limit
To set a limit different from the factory setting, proceed
as follows:
1. Determine the desired temperature range limit or lock-
ing temperature. Select the appropriate number on the ad-
justment knob to match the desired temperature setting. See
Fig. 5.
