APPLICATIONS

• VAV and by-pass units control

with modulating tri-

state floating output

Single stage of auxiliary reheat

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%.

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.

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.

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.
