The THR 10-100 is equipped with two 10 to 50 kW
modules. These modules are controlled by their res-
pective LGM. The RVA 47 manages the cascade
between the two LGMs according to input and at-
mospheric conditions.
The RVA 47 regulator determines a boiler flow tem-
perature according to atmospheric conditions or ac-
cording to connected RVA 46 (option) regulator
inputs and transmits it with a flow regulation to the
first LGM (master) via an OCI 12 interface. Accord-
ing to the difference between the actual temperature
and the boiler’s temperature setting, the second
module (slave) is either selected or not selected.
The THR 10-100 was originally pre-equipped to ac-
commodate two RVA 46 regulators(options). These
zone regulators, which can communicate with the
RVA 47, can control an entire heating system (heat
production and multiple zone heating by operating a
pump or a mixer valve). Such a heating system can
feature up to 40 regulators.
Thanks to this communication ability, only one out-
side sensor is required in the whole system.
Note:
- The heating system can be completed by adding
other ZH 46 type control boxes. - see section VIII
