Carrier 33CS250-rc plus 33CS250-re wireless thermostat
Up for sale is a Carrier Debonair Wireless - Commercial model 33CS250-RC WIRELESS THERMOSTAT AND QTY. (3) 33CS250-RE REMOTE RECEIVERS. They are used and in good condition but need a good cleaning (also the wireless thermostat has some yellowing of the plastic due to sunlight exposure whitch does not effect performance).
The Debonair commercial programmable wireless thermostat provides the following features and benefits:
compatible with electric heat, gas heat, and heat pump operation
transmits up to 500 ft through walls and ceilings
seven-day programmable clock with 4 time periods per day
one transmitter can transmit to a maximum of 16 receivers
up to 4 transmitters work with one receiver
holiday scheduling (up to 99 consecutive days)
copy command for programming schedules
three security levels with keypad lockout
large Thermoglow configurable display
heating and cooling operation LED
zone temperature control to 1-degree accuracy
Neverlost non-volatile memory
five-minute compressors time guard
adjustable heat/cool set point limiting
pre-occupancy purge (0-3 hours)
Wireless remote control thermostat
Back lit (glow in the dark), large numbers, and shows the heating set point, cooling set point, and room temperature
Can be manually operated or programmed for energy savings
Up to 4 thermostats can be used with one receiver
Transmits up to 500 feet, through walls and floors
The receiver is easy to install and is wired just like a standard 24VAC thermostat. Once the receiver is installed, the thermostat can then go anywhere in the building, and it will transmit radio signals back to the receiver. The transmission range is up to 500 feet, and it works through walls, floors, ceilings, etc. The temperature sensor is located on the thermostat, so place the thermostat where temperature control is most important to you - your bedroom, the boss's office, a baby's room, etc.
Auto Changeover, 2-Stage Heat & 2-Stage Cool for use with gas / electric or heat pump systems.
Thermostat is completely wireless, receiver can be mounted at unit or at old thermostat's location.
Up to 4 thermostats can be used with one receiver. Transmits up to 500 feet, through walls and floors. Transmits at 418MHz using pulse code modulation - won't interfere with other wireless systems Sender uses two AA batteries 7 Day Programmable with 4 time periods per day, copy command and holiday mode Dual-setpoint with adjustable deadband (1 to 6 degrees) and temperature sensor calibration. Programmable Fan All programming stored in nonvolatile memory. Thermoglow Electro-luminous Display. Display shows heat and cool setpoints, mode, and room temperature simultaneously. 5 minute compressor time guard and adjustable cycle limit, both overrideable for servicing equipment Setpoint adjustment range from 35 to 99 F, sensing range from 32 to 99 F. 64 house codes allow installation of up to 64 systems within transmit range with no interference.
Hard-wired (Low voltage) connections between heating/cooling equipment and thermostats have many limitations that can now be overcome with wireless technology. Wireless thermostats add the flexibility to control the temperature in one or more locations of your choosing. They are ideal for equipment retrofits, additions, and for overall improvement in HVAC performance in new home construction. Wireless systems typically consist of the thermostat (sensor) itself and a receiver. Most come with one or more remote controllers.
The convenience of installing a system with wiring behind the walls is one the largest benefits of this technology. Another is the flexibility to place the thermostat in any number of locations. A third benefit is the ability to add higher levels of control without much effort. The manufacturers also claim significant savings in energy use due to better control over the system. Depending on the system you are comparing, the complexity of the system and corresponding level of control, claims of energy savings can exceed 20%. The less complicated systems will operate similar to a conventional thermostat system. In either case, there will likely be initial installation cost savings, especially for retrofits.
This thermostat and 3 wireless receivers were recently removed from service in excellent working condition in order to install a different type of system.
