Siemens room thermostats for fan coil units come in several series. This guide compares three models we stock: the RDG200T, the RDF600 and the RDF800. All three control heating and cooling of a room through a fan coil unit and have a built-in temperature sensor.

| Operating voltage | AC 230 V | AC 230 V | AC 230 V |
| Control outputs | triac: On/Off, PWM or 3-position | On/Off or 3-position | On/Off or 3-position (selectable by application) |
| Fan | 3-speed, 1-speed or DC 0…10 V | 3-speed or 1-speed | 3-speed or 1-speed |
| Multifunctional inputs | 3 (X1, X2, X3) | 2 | 2 |
| Applications | fan coil units (2-pipe, 2-pipe with electric heater, 4-pipe), chilled/heated ceilings, compressors in DX equipment | fan coil units (2-pipe, 2-pipe with electric heater, 4-pipe), compressors in DX equipment | fan coil units, chilled/heated ceilings, compressors in DX equipment |
| Operation | buttons, display | buttons, backlit LCD | touch screen, large backlit display |
| Time program | weekly scheduler | RDF600T only: 7-day program with 8 timers | not listed in the data sheet |
| Extras | commissioning with the Siemens smartphone app PCT Go; 20 h power reserve clock | RDF600T: infrared receiver (remote control IRA211 sold separately) | window contact and presence detector functions; commissioning wizard |
| Mounting | wall mounting on a mounting plate; ARG200 adapter if no conduit box is available | round box, min. 60 mm diameter and 40 mm depth | round box (min. 60 mm) or recessed square box (60.3 mm fixing centres, min. 40 mm deep); RDF800/NF for square boxes only, needs a separate mounting frame |
How to choose
- Choose the RDG200T if you need the most flexible controller: chilled/heated ceilings in addition to fan coils, PWM or 3-position control outputs through the triac, DC 0…10 V fan control, three configurable inputs, or commissioning with a smartphone app. The related RDG260T (24 V, DC 0…10 V control outputs) is available for modulating valve actuators.
- Choose the RDF600 for a straightforward fan coil thermostat with a backlit display and a round flush-mount box. Pick the RDF600T if you want a 7-day time program (8 timers) and an infrared remote receiver.
- Choose the RDF800 if user comfort and appearance matter, for example hotels and offices: touch screen, large display, window contact and presence detector functions, and commissioning via a wizard.
Check before ordering
- Operating voltage and the type of valve actuator (On/Off, 3-position, or DC 0…10 V).
- The mounting box in the wall (round or square). For the RDF800/NF a mounting frame must be ordered separately.
- The valve actuators are not included. Optional sensors (for example the QAH11.1 cable temperature or changeover sensor) are ordered separately.

Siemensi ruumitermostaadid ventilaatorkonvektoritele (fan coil) on mitmes sarjas. See juhend võrdleb kolme poes olevat mudelit: RDG200T, RDF600 ja RDF800. Kõik kolm juhivad ruumi kütet ja jahutust fan coil seadme kaudu ning neil on sisseehitatud temperatuuriandur.

Kuidas valida
- Vali RDG200T, kui vajad kõige paindlikumat kontrollerit: lisaks fan coilidele jahutus-/küttelagi, triac-väljundid (PWM või 3-asendiline), DC 0…10 V ventilaatori juhtimine, kolm seadistatavat sisendit või seadistamine nutitelefoniga. DC 0…10 V juhtväljunditega ajamite jaoks on olemas RDG260T (24 V).
- Vali RDF600, kui vajad lihtsat fan coil termostaati taustavalgustusega ekraaniga ja ümmarguse süvistatava karbiga. RDF600T lisab 7-päeva ajaprogrammi (8 taimerit) ja infrapuna vastuvõtja.
- Vali RDF800, kui oluline on kasutajamugavus ja välimus, nt hotellides ja kontorites: puuteekraan, suur ekraan, akna kontakti ja kohaloleku anduri funktsioonid ning seadistusviisard.
Kontrolli enne tellimist
- Toitepinge ja ajami tüüp (On/Off, 3-asendiline või DC 0…10 V).
- Seinas olev karp (ümmargune või nelinurkne). RDF800/NF jaoks tuleb raam eraldi tellida.
- Ajamid ei kuulu komplekti. Lisaandurid (nt QAH11.1) tellitakse eraldi.
Abi valikul? Tooted valib ja ostukorvi paneb klient ise; valikut aitavad teha andmelehed, tootelehed ja meie juhendid.
