CONTROL SIEMENS: RVS 63.283
BASIC CONTROLS OF THE CONTROLLER - - Boilers Cascade (by means of data bus) - - Circuits: (up to a maximum of two mixing valves) 2 2 Heating circuits with mixing valve (Circuits 1 and 2) 1 1 D.W.H.S. circuit (managing the primary pump or a primary mixing valve) 1 Heating circuit managing ON/OFF of the pump (HCP) - Added options / applications by means of output of programmable relay: 1 circuit pump by time program. 2 circuits pumps function of program time set. Other use due to program relays.
Example: Cascade of three boilers ADI: 3 boilers ADI 3 units Clip OCI 420 + wire AGU 2.104A109 (not included in the boilers supply, to be ordered, and later to be fitted inside every boiler). 1 unit controller RVS 63 (includes: controller, display and cable between both). To be ordered. 2 units temperature sensors 1 unit External Weather temperature (if non-freezin control is required or weather compensation)
