17. Heating or cooling module
Operation
The module has four outputs to operate control valves (e.g. electronic valves at 230 Vac or 24 Vdc), 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 electronic valves as
well as the lag time 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.
Permitted loads
The module can be used to switch potential-free boiler contacts. Check the table below to find out the maximum load for
each type.
J. CHANNEL LEDs One LED per channel. The CHANNEL LED lights up in TEST mode when the output is
activated.
K. STATUS LED 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.
See
Error codes on page 112 .
The module does not change the settings of the heating or cooling system.
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.
Type of load Maximum RMS current
inductive loads (circulation pumps …) 6 A
capacitive loads 10 A
resistive loads (electric heating units …) 16 A
