According Honeywell, for one pipe heating system is acceptable to use thermostats with Kv = 1,2 (when set to mode 2 K). Better if these values exceed the 1.5 and approach 2. Such indicators are characterized Thermostats Danfoss model RTD-G (for installation on the nominal diameter hoses 15, 20 and 25 mm) and a RTD to be embedded in space heaters, the company Honeywell model THX9321R5000 (under the diameters podvodok 15, 20 and 25 mm) and for embedding in devices Honeywell THX9321R5000, firm Komap “model« Comap 830 3 / 4 “) and a special thermostat firm Haymayer for nozzle diameter of 20 mm and a firm” Honeywell “H model (for a nozzle diameter of 15 , 20 and 25 mm). In one-pipe heating systems are very beneficial, as indicated, to apply adapted to conditions in USA three-way Honeywell THX9321R5000 thermostat firms Honeywell and LUX.
Almost any Honeywell THX9321R5000 thermostats can be used when using H-shaped units, but in this case must be carefully selected pumps respective pressures and capacities.
