BMS configuration screen for th-Tune indoor terminals, with the recommended values for the
correct operation of the heat pump.
MENU 2.4.4 Manual conf.
This allows the activation of the relays that control various heat pump devices and their regulation as
required. According to the ecoGEO heat pump model, one or another screens appear.
MENU 2.4.4.1. Digital Inputs
The digital inputs of the heat pump mean it can be controlled according to a number of criteria
that depend on the installation. The first, identified on screen as THERMOSTAT IMPUT DI1 is
used to enable the on-off control of the heat pump by relay type thermostats. When it is
enabled, its operating logic must also be chosen, NC or NO (normally closed or normally open).
If you choose the NC option, the input must be entered in contacts 38 and 39 (see section 8.3)
so the pump is activated in an open circuit. If the NA option is chosen, the input required for
the activation of the pump is a closed circuit. For ecoGEO C3 model, the same thermostat can
be used to control the production of active heating and cooling. This requires taking into
account the production of heating when choosing the strategy.
The other input available, ecoGEO IMPUT DI2, allows external control of the heat pump. The
logic for this operation input is analogous to that explained in the previous case.
MENU 2.4.4.2. Brine pump
For all ecoGEO heat pump models. The status of the brine pump (On/Off) and its speed can be
defined.
MENU 2.4.4.3. Heating pump
For all ecoGEO heat pump models. The status of the heating pump (On/Off) and its speed can
be defined.
NOTE
th-Tune indoor terminals and conventional relay type thermostats for controlling the pump cannot
coexist. This may cause the machine to malfunction.
The signal for THERMOSTAT IMPUT DI1 should be a voltage-free signal.
The signal for ecoGEO IMPUT DI2 should be a voltage-free signal.
