NOTES:
All models are available with or without factory installed valve clusters. Above are “standard” 2-way and 3-way valve clusters.. Contact the factory for other options such as circuit setters, strainers, auto-flow valves, etc.

Accurate, Efficient, and Quiet Fan Coil Operation

The new Autospeed 24V™ thermostat (part’s # T200 and T201) provides 24V AC single stage temperature control of 2 pipe and 4 pipe fan coil applications. The T200/T201 thermostat offers maximum comfort and efficiency by automatically selecting the appropri-ate High, Medium, or Low fan speed, depending on room temperature and thermostat temperature setting. This automatic fan speed control not only brings the room temperature to the desired set point quickly, it maintains the room temperature with the most efficient fan speed selection. Once the desired room tempera-ture is achieved the fan coil operates on low speed for extremely quiet operation. The fan coil control board (which is factory installed in all CW units) is a circuit board that provides control of a 3-speed line voltage fan motor. The control board allows the thermostat to control the fan motor even though, by itself, the ther-mostat does not have the amperage capability nor the voltage rating capability to control the fan motor.

T200/T201 Thermostat Features

Compatible with 2 pipe and 4 pipe fan coils: Series HBC/PHBC/RHBC/CHBC,
MB/MB-HW, HYB/PHYB, and CW/CH-HW/CWE
Cycle fan or continuous fan operation
T200-Manual Heat / Cool changeover switch
T201-Automatic Heat / Cool changeover switch
Large LED digital display
Allows less expensive 24V control wiring from the fan coil to the thermostat, rather than larger, more expensive line voltage wiring.
3-speed fan operation, with speed indicator lights
Fan speed determination:
- If room temperature is 4 degrees (F.) off thermostat set point, fan will operate on High speed.
- If 3 degrees off set point, fan will operate on Medium speed.
- If within 2 degrees of set point, fan will operate on Low speed.
One or 3 hour Auto override – Fan speed defaults to “Auto” mode after 1 hour if the user manually changes it to a particular fan speed.
Temperature set range: 64-88 degrees F.
Adjustable high and low temperature set points
Selectable Fahrenheit / Centigrade display
Power switch turns system off/on
Requires 7-wire 24V thermostat wire
No batteries required
Set points are permanently retained in memory in case of power interruption
Simple operation
Mercury Free
Wall plate included
