and one for night operation

• Two independent setpoints control

day operation and night setback

• Adjustable stops can be set to

limit travel of day setpoint

adjustment

• Constructed to corrosion resistant

materials

• Glass-filled Delrin back plate acts

as thermal resistor to reduce cold

wall effect
