Comfort™ Pro Commercial Non-Programmable Thermostat 33CSCNACHP-01
Comfort™ Pro Commercial Non-Programmable Thermostat
33CSCNACHP-01
Carrier’s commercial non-programmable thermostats offer flexibility, quality, and reliability. The wall-mounted, low-voltage thermostat maintains room temperature by controlling the operation of an HVAC (heating, cooling and ventilation) system. This thermostat can be used to control heat pump, air conditioner or water source heat pump operation. Separate heating and cooling set points and auto-changeover capability allow for energy savings.
- Non-mercury, non-lead based electronic controls built into slim plastic enclosure
- 2-Stage heat/2-stage cool with auxiliary heat (air conditioning, heat pump, and water source heat pump units)
- English/metric unit selection
- Proportional integral control of heating and cooling stages
- Remote sensing and averaging
- Keypad lockout security with passcode protection
- 24 vac or battery powered user configured settings are stored for an unlimited period of time
- Expanded backlit display features mode and equipment status, and outdoor-air temperature
- Hospitality mode — display user set
- Point in place of actual temperature
- Random start
The thermostat allows separate heating and cooling set points. The thermostat stores installer configurations. In the event of power interruption, the internal memory stores set points for an unlimited time. When 24 vac is not available to power the thermostat, batteries can be added.
The Comfort™ Pro commercial non-programmable thermostat is capable of displaying the outside or supply-air temperature using the remote sensor input.
NOTE: Designed and assembled in the U.S.A.

Appearance: plastic material; white smooth cover
Weight: approx. 1/2 lb (0.23 kg)
Lead-free design
Power Requirement
24 vac 50/60 Hz at 3 va RC/RH compatible
AA alkaline battery power also available (batteries not included)
Environmental Requirements
Operating temperature: 32 to 104 F (0° to 40 C)
Storage: –40 to 135 F (–40 to 57 C)
Humidity: 0 to 95% RH (relative humidity), non-condensing
Agency Approvals
FCC Part 15, Subpart J compliant
CE mark approval
Electrical Characteristics
Inputs: 24 vac, 50/60 Hz, 3 va
Outputs:
- Minimum Load = 1000 ohms
- Maximum Load = 2.0 A, 50% pf (power factor) Inductive
- Nominal Load Capacity = 1.5 Amps
Temperature Control
The thermostat uses proportional integral calculation to determine the number of stages required for heating or cooling (and fan speed for fan coil units) to provide accurate temperature control.
