Adjusting Heater Offsets
The heater offset can provide substantial energy savings if correctly
adjusted according to the outside temperature. It is the number of
degrees below the set point at which the heating units turn off (see
diagram above). The heater 1 and 2 offsets can be adjusted between
-10
o
F and 20.0
o
F (-5.6
o
C and 11.1
o
C). If the heater offset
is negative, the heating units will turn off at temperatures above the
set point. If cascading heating is used, only Heater 1 offset is used.
Set selection knob to
HEATER 1 — OFFSET/DIFF.
or
HEATER 2 — OFFSET/
DIFF
. The current heating
offset is displayed, alternat-
ing with the letters "
OFt
".
Use the adjustment knob to
adjust the offset to the de-
sired value.

Adjusting Heater Differentials
The heating differential is the temperature difference between the
moment the heater units turn on and the moment they turn off (see
diagram above). The differential can be adjusted between 0.5
o
F and
20.0
o
F (0.3
o
C and 11.1
o
C).
Set the selection knob to
HEATER 1 — OFFSET/DIFF.
or
HEATER
2 — OFFSET/DIFF
. The current heater offset is displayed,
alternating with the letters "
OFt
".
Press the push-button. The heater differential is displayed,
alternating with the letters "
diF
".
Use the adjustment knob to adjust the differential to the desired
value.
