Valve Control With Room Thermostat With:
Cool / Heat Auto Changeover Input
24 VAC POWER AND FLOATING ACTUATOR TYPICAL WIRING
•
Power Supply 24 Vac -15% +10% 50/60 HZ 2 VA
•
If operation of the actuator is reversed, flip the reversing switch on
the actuator or reverse wires #5 & #6.
•
Note: terminals 2 and 3 can be wired together between each
thermostat if polarity is respected
•
Important: if using a common transformer, respect polarity ( Common
and 24 Vac between thermostats and actuator )
CHANGEOVER INPUT TYPICAL WIRING
1 SUPPLY CHANGEOVER SENSOR PER THERMOSTAT ( 1 SUPPLY SENSOR PER THERMOSTAT )
Auto changeover input using an S60, S70 duct supply sensor or S90
immersion supply sensor
• Supply
temperature
> 78°F (26°C) = Heating mode
• Supply
temperature
< 75°F (24°C) = Cooling mode
• Hysterisys is 3°F (2°C) between heating and cooling
MULTIPLE TRANSFORMERS ( 1 DRY CONTACT FOR ALL THERMOSTATS )
Open contact = Cooling mode. Closed contact = Heating mode
SINGLE TRANSFORMER ( 1 DRY CONTACT FOR ALL THERMOSTATS )
Open contact = Cooling mode. Closed contact = Heating mode
