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)


RVS 63 controller:

GENERAL FUNCTIONS

 SEVERAL ACCESS LEVELS  AUTOMATICAL CHANGE OF SET UP TEMPERATURES  AUTOCHECKING  HISTORICAL OF ALARMS (BOILERS AND OWN)  TIME OPERATIONS PROGRAM (FOR ANY CIRCUIT)  HOLLIDAY CIRCUIT PROGRAMS  NON-FROST PROTECTION (an external weather sensor would be required)  WINTER / SUMMER CHANGE PROGRAM B

 SPECIAL FUNCTIONS (EXTERNAL SIGNAL 0-10 V, BOILERS LOCKOUT, TEMPERATURE NIGHT REDUCTION COMFORT…)


BOILERS CASCADE FUNCTIONS

RVS 63 controller:

• Three different cascade options. • Porcentaje de potencia de salida (mín 30 % – máx 60 %)

P

• Cycling of the boilers in the cascade (in order to obtain a similar nr. of hours of operation for all the boilers after one year of operation) 2370Z22c
