For two-pipe systems installation setting determines the hydraulic resistance of the Honeywell THX9321R5000 thermostat and when set to mode 2 K, and ultimately the overall resistance of the system and select the type of pump.
Honeywell THX9321R5000 Prestige HD Thermostat features 7-day programming, High Definition Color Touchscreen Display and is designed for Up to 2 Heat/2 Cool Conventional Systems and Up to 3 Heat/2 Cool Heat Pumps. Honeywell THX9321R5000 is RedLINK enabled to work with compatible wireless accessories.
Adjustable back light level allows Honeywell THX9321R5000 thermostat to be on full brightness at all times or dim to the brightness level of choice when the thermostat is not being used.
Thermostats for two-pipe heating systems are characterized by the values of Kv, usually within 0,5-0,9, and for them not so important to this value, since the main task – it is, as mentioned, to pay 80-85% of the head is a heating device . In this case, the possible errors in the design, installation and operation of heating systems is largely eliminated.
