ELECTRONIC THERMOSTATS
C1011
• One floating output
• Supply air temperature auto changeover input
DESCRIPTION
The C1011 series thermostats are microcomputer-based,
proportional and integral (PI) devices with one floating
(incremental) output. It can be used with most controlled
devices in the HVAC industry that are compatible with this
signal. Typical applications would be to control a floating
VAV or valve actuator. The thermostats also contain a berg
jumper for the actuator stroke time from full open to full
close.

Notes:
• Order changeover sensor separately.
• Vertical mounting is standard.
MODULATING FLOATING OUTPUT
This output is designed to give true PI modulation out of
floating actuator for VAV dampers and valves.
The thermostat is designed for operation with actuators that
have a running time of 1.5 to 2.5 minutes for the full open /
close stroke time.
The output is normally cooling but can be reversed to
heating mode with 2 different methods:
• Auto changeover to heating mode with a supply
sensor.
A remote supply sensor can be used for each thermostat.
Supply temperature
> 78°F (26°C) = heating mode
Supply temperature < 75°F (24°C) = cooling mode
Hysterisys is 3°F (2°C)
• Auto changeover to heating mode with a dry contact.
A closed contact on the changeover input will change
operation of the floating output to heating mode.
Open contact = cooling mode
Closed contact = heating mode
