RVD260-A

Multifunctional heating controller for use in district heating substations and district heating plants with LPB and M-bus communication. Suited for 2 heating circuits with d.h.w. heating in instantaneous systems or with storage tank. 14 programmed plant types. Operating voltage AC 230 V.

Same functionality as RVD250‚ but with the following extra features:

• 2 heating circuits
• Without precontrol in interconnected systems
• 3 independent switching programs each with 3 occupancy times per day

Plant-specific:
– Precontrol internal control loops
– 2 heating circuits (mixing and / or pump heating circuit): Control of flow temperature‚ optionally weather-compensated / weather- and room temperature-compensated / room temperature-compensated
– D.h.w. heating with selectable priority:
