3-way valve regulator R3V-421 ELEKTROBOCK - 4421

Features of the R3V-421 controller:

NEW VERSION 11.03 (ON SALE FROM 1.12.2014 )

IMPROVED VERSION IN TERMS OF USER SETTINGS.

The controller allows you to control three-way/four-way valves, pumps, switch the boiler and regulate the temperature according to the selected function, based on the connected sensors (max. 8).
It can be used, for example, in the following systems:
- single and multi-circuit systems (radiators, underfloor heating)
- for discharging the storage tank
- for solid fuel boilers (regulation with respect to return temperature)
- where the heat source does not allow regulation according to the outdoor temperature (equithermal regulation).

Types of regulation:

• Room temperature-dependent control with temperature sensor (PI control)
• Control according to temperature downstream of the valve with respect to the room thermostat
• Weather-compensated control with room temperature compensation with temperature sensor
• Weather-compensated control based on outdoor temperature with respect to the room thermostat
• Return temperature control with temperature sensor
• Return temperature control with respect to the room thermostat
• Service mode
• Summer mode

Advantages of R3V-421:

• 7 weekly programs with 6 temperature changes per day
• language selection (CZ/EN)
• AUTO/MANU/OFF mode selection
• monitoring of maximum boiler temperature
• valve adaptation after switching on the regulator
• Clock backup after power failure is more than 4 hours
• selection of maximum valve step
• antifreeze protection
• automatic protection against limescale
• short-term temperature change
• information about the temperatures on the sensors, the calculated temperature on the valve and the approximate value of the valve position in % for each connected circuit
• power supply 5 V/DC, 500 mA (AD05-DIN power supply not included)
• possibility of connecting up to 8 temperature sensors (the package includes KO, VT, M1, V1, Z1 sensors, others can be purchased at www.elbock.cz)
• possibility of connecting a thermostat for remote control
• max. output load (I max) is 5 A
