Regulator incalzire Siemens Landis & Steafa R panou control

vine exact ca in poze la cutie .nou
se foloseste la reglarea temperaturii si a ventilatiei

utilizare
In ventilating and air conditioning plants with
· hot water heating coils or electric air heater batteries
· direct expansion cooler batteries or chilled water cooling coils
· recirculated air dampers or heat recovery (HR) equipment
The R is used to:
· control
- the room-supply air temperature or extract air-supply air temperature (cascade
control) with adjustable minimum and maximum limitations
- the room-supply air temperature or extract air-supply air temperature (cascade
control) with room or extract air-dependent shifting minimum and maximum
limitations (displacement ventilation)
- the supply air temperature
- the CO2 /VOC content of the room air (demand controlled ventilation)
- single- or two-speed fans
- air coolers
- chillers
- HR equipment
- hot water heating coils (with preheating)
- electric air heater batteries (with fan overrun)
- circulators in hot or chilled water circuits (load- or outside temperature-dependent)
- air damper actuators (with recirculated startup circuit for modulating dampers)
- regulating units in hot and chilled water circuits

· supervise
- the air flow in air ducts
- overloads of circulators, fans and chillers
- overtemperatures of electric air heater batteries
- risk of fire or smoke
- risk of frost
