Operation

The module has four outputs to operate control valves (e.g. zone valves at 230 V AC or 24 V DC), pumps, electric heating
units or individual cooling units (e.g. air-conditioning units or fan convectors) in four different zones or rooms. This allows
you to apply different heating or cooling settings to each one of the four zones or rooms fitted with a Niko Home Control
thermostat.
The module uses one output to control the heating or cooling system. When the module receives a heating or cooling
request from the Niko Home Control thermostat in one of the zones or rooms, the H/C contact of all the modules will be
closed which then activates the central boiler or cooling unit. The most centrally located boilers or cooling units are fitted
with an input contact (e.g. a telephone or boiler contact) for this purpose. If not, a special regulation module will be added
to the central boiler or cooling unit. In installations with a hot water reservoir, the circulation pump will be activated.
To avoid conflict in the installation, the module takes into account the opening and closing times of the zone valves as well
as the lag time of the heating or cooling system .
The module does not change the settings of the heating or cooling system.
Sizing
Each module controls the heating or cooling in four different zones or rooms but cannot perform both functions at the
same time. Two separate modules will be required to use the heating function at the same time as the cooling function.
One extra module is required for every four additional zones or rooms to be heated or cooled.
A maximum of 12 zones or rooms can be heated and cooled. In other words, a maximum of six modules can be used per
installation.
If a heating or cooling request is received for one of the zones, the H/C contacts of all modules will be closed.
This setting cannot be changed.
Permitted loads
The module is suitable to switch potential-free boiler contacts. Check the table below to find out the maximum load for
each type.
Type of load
inductive load (circulation pumps ...)
capacitive load
resistive load (electric heating units ...)

Heating or cooling module
The function of this button is twofold. In addition to the function described under
"H" this button is also used while programming the installation to send the unique
address of the module during the addressing phase.
One LED per channel. The CHANNEL LED lights up in TEST mode when the output is
activated.
The STATUS LED lights up in TEST mode when the module is connected correctly and
is functioning properly. If an error occurs, the LED will blink to indicate an error code.
