temperature. Start-up of the function can be related to

the power supply tariffs switch-over, either via time or

external command. The advantage consists in a

possibility to accumulate heat under better conditions, i.

e. when the air temperature is higher.

Bivalent source:

Supports electrical cartridges in flow or tank

Supports exernal sources (existing gas, electrical or

other boilers)

Three-level or single-level bivalence control

Heating system:

Solely equithermal control (acc. to the ambient

temperature only)

Space temperature control

Equithermal control in relation to space

One controller can control up to 2 heating circuits and

one pump circuit

Each heating circuit can be controlled independently via

its own space unit

Existing thermostats with ON/OFF modes can be used

More heating circuits can be added via the RVS zone

controllers

Possible integration with master controllers, i. e. control

of heating circuits per room

Hot water heating

Water heated in the tank with a separate boiler

Water heated in the surge tank with a floating boiler

Internal exchanger or external exchanger for boilers

without an internal exchanger or with insufficient capacity

Flow heating

Force heating

Combination with solar heating

Control of electrical heater in the boiler or external source

for hot water heating

Function of heat transfer between the surge tank and

boiler (typical situation: the tank is heated by the solid

fuel boiler or hot water wood stove)

Solar system:

Over 50 ways of connection

Definition of 3 off-takes (hot water heating, surge tank,

swimming pool)

Integration with the heat pump (can meanwhile work as a

secondary source for hot water heating)

Swimming pool heating:

Supported

Wood stove:

In case the tank is heated from the stove, the heat pump

is off

Function of overheated tank cooling

If combined with another RVS, the wood stove or solid

fuel boiler circulation pumps can be controlled directly,

including other functions, e. g. source extinction

monitoring.

Cooling:

Supports both passive and compressor cooling

Supports heating and cooling in the both two-pipe and

four-pipe networks

Supports alternating cooling and heating of hot water or

swimming pool

Supports passive cooling at ground to water systems

Dew point check

Dehumidifier control

Cascade:

Standard control supports connection up to 16 heat

pumps or other sources in the cascade mode

Various types of sources are supported in the cascade

(gas, electrical or fuel solid boilers)

Gas boilers with Siemens control can be connected with

our heat pumps to the cascade. The following brands are

available on the Czech market: Geminox, Brötje, Baxi

and Viadrus, equipped with the LMU units.

Other functions:

Entry of ripple control (electrical heating blocking)

Entry of external command on heat 0 – 10 V, mode

switching, heat pump start-up...
