Electronic Thermostat

APPLICATIONS

• VAV and by-pass units control floating output

• Heating/Cooling change over with supply temp. sensor

• Single stage of auxiliary reheat

with modulating tri-state

ADVANCED DESIGN AND PI CONTROL

Advanced PI control thermostats provides precise temperature control and eliminates wasted energy caused by the typical On / Off cycling in conventional thermostats. Thus the room occupant is able to reduce the thermostat setpoint to the lowest comfortable setting. The result is energy savings ranging from 5% to 10%.

COVERS

Factory standard scale is 10°C to 32°C for horizontal mounting. °F & °C scales are available on special order for horizontal or vertical mounting. The thermostat and the terminals are an integral part of the cover. The cover hooks onto the base for easy service and is locked in place using a security screw.

MODULATING TRI-STATE FLOATING OUTPUT

For use with tri-state floating actuator (CW/Off/CCW) having a 1 to 2 minutes timing per 90° of rotation. This is a true multi positions modulating output. It gives performances which is equivalent to more expensive 0 to 10 Vdc type output.

HEATING / COOLING CHANGE OVER

The output is normally cooling but can be reversed to heating mode with 2 different methods:

Auto change over to heating mode with the supplied sensor.

1 change over sensor is used for each thermostat. Supply temperature < 75°F (24°C) = cooling mode Supply temperature > 78°F (26°C) = heating mode Hysterisys is 3°F (2°C) Auto change over to heating mode with a dry contact. A closed contact on the change over input will change operation of the tri-state output to heating mode. Open contact = cooling mode Closed contact = heating mode

SINGLE STAGE OF AUXILIARY REHEAT

To be used with On/Off 2 position 24 Vac devices like:

• On/Off N.C. electric valves

• Electric duct heater relays

• Electric base board relays

See and study wiring diagrams carefully to wire reheat devices using a separate power source.
