Firstco T200 Autospeed 24V Digital 3-Speed Wall Thermostat

The Firstco T200 (also known as TF85L-200) is an Autospeed 24V digital wall thermostat designed specifically for single-stage temperature control of 2-pipe and 4-pipe fan coil systems. This intelligent thermostat automatically selects the optimal fan speed based on room temperature variance from the setpoint, delivering exceptional comfort and energy efficiency.

Automatic Fan Speed Control:

• When room temperature is 4°F or more from setpoint, operates on High speed
• At 3°F from setpoint, switches to Medium speed
• Within 2°F of setpoint, runs on Low speed for whisper-quiet operation
• Speed indicator lights provide visual feedback of current fan operation

Key Features:

• 24V AC single-stage heating and cooling control
• Heat/Cool system switch with manual or auto 3-speed fan control
• Separate on-off switch for convenient operation
• Temperature setpoint range: 64-88°F
• Temperature accuracy: ±1.8°F
• Operating voltage: 18-30 VAC, 50/60 Hz
• Ambient temperature range: 50-122°F
• One or 3-hour auto override feature returns fan to Auto mode after manual adjustment

Installation Benefits:

• Uses cost-effective 24V control wiring instead of expensive line voltage wiring
• Compatible with Firstco fan coil series: HBC/PHBC/RHBC/CHBC, MB/MB-HW, HYB/PHYB, and CW/CW-HW/CWE
• Works with factory-installed fan coil control board that manages 3-speed line voltage fan motors

The T200 thermostat provides professional-grade temperature control with intelligent fan speed management that maximizes comfort while minimizing noise and energy consumption. Its automatic speed adjustment ensures rapid temperature recovery when needed and ultra-quiet operation once the desired temperature is achieved.
