3. BOILER CONTROL PANEL
INFORMATION:
For hot water installation:
o Maximal operating temperature: 95°C when the boiler is managed by a
Navistem B1000 ou B2000.
o Maximal operating temperature: 105°C if the regulation system is compatible
with this work.
In any case, this device has been designed according to EN 14394. The safety limit
thermostat does not exceed 110 °C.
3.1. Description
Several types of control panel are assigned to Melbury
HE.
The NAVISTEM B1000 control panel without heating
regulator is used to manage the operation of a burner
at 1 or 2 stages using a double regulation thermostat.
It does not protect the boiler against condensation in
the steel heater housing, ensuring a minimum return
temperature of 50° C with oil and 60° C with gas.
The NAVISTEM B2000 control panel with RVS 63
heating regulator enables management of the
operation of the burner (speed 1 / 2 or modulating),
heating circuits and domestic hot water production.
The RVS 63 regulator is equipped with digital logic
enabling the boiler to be protected against cold starts. It
also enables management of the flow and temperature
of return water by acting on the three-way valves of the
heating circuits or three-way valve for heating the boiler
return temperature.
The control panels are supplied ready to be connected.
The regulators must be set according to the
recommendations in the instructions provided in the
control panel to protect the boiler against condensation.
Settings must also be adapted to comply with the
hydraulic system configuration (circuits for heating,
domestic hot water, etc.).
The steel sheet housing is ready to be mounted on top
of the boiler cover or on the carrier located on the side
cover.
The electrical diagram is attached to the control panel.
