P6861HG-M is a horizontal thermostat. It refers to the standard model with built-in temperature sensor, optimized for straightforward manual or automatic changeover in 2-pipe fan coil applications.  This model uses a basic on/off control algorithm for the water valves in a fan coil system. This means the valve is either fully open or fully closed to regulate temperature. P6861HG-M replaces T6861H2WG-M
P6861HG-R is a horizontal thermostat. It supports a remote sensor or remote setback input, allowing for temperature monitoring away from the unit, making it suitable for larger rooms or specific positioning requirements.  P6861HG-R replaces T6861H2WG-R
It features a large LCD with a green backlight, 3-speed fan control (manual/auto), energy-saving modes, and direct installation on 86x86mm boxes, making it suitable for hotels, residential, and office buildings.
The device offers flexibility with selectable room temperature or setpoint display and allows for manual or automatic fan speed control.
