VDC to R2 indexes T1 to the auxiliary flow limit.
Cover
NOTE: When using a blank cover (without a
window), remove the finger pads on the
setpoint sliders. Hold the slider in place,
insert a small flat blade screwdriver into
the slot in the metal slider. Twist the
screwdriver slightly to pop the pad off.
With the window style covers, a symbol-coded label
strip is included to apply to the covers for setpoint
indication.
1. Remove the window from the cover by applying
light pressure on its underside and flexing
upward.
2. Peel off correct identity label from the strip of
labels provided.
3. Position the label on the cover’s recessed area.
4. Snap window back in place.
5. Slide cover onto base.
6. Locate the setscrew on each of the thermostats
short sides.
7. Using a 1/16" hex wrench, turn setscrews outward
CCW until the cover is secure. (Turn setscrews
CW to remove cover.)
