4.2. PROGRAMS
ECOFOREST ecoGEO heat pumps have three main operating programs, which are described below.
WINTER PROGRAM
The heat pump only allows activation of the operating modes HEATING, DHW, LEGIONELLA
PROTECTION, POOL and FAULT. FREE COOLING and ACTIVE COOLING operating modes are not
permitted.
SUMMER PROGRAM
The heat pump only allows activation of the operating modes FREE COOLING, ACTIVE COOLING,
DHW, LEGIONELLA PROTECTION, POOL and FAULT. HEATING operating mode is not permitted.
AUTO PROGRAM
The heat pump automatically selects one of the WINTER / SUMMER operation programs based on
several environmental parameters. In the example in Figure 4.2 if the outside temperature rises above
26 ° C over a period of 5 hours an automatic program to SUMMER WINTER program occurs. If the
outside temperature drops below 12 ° C over a period of 5 hours an automatic program to WINTER
SUMMER program occurs.

of
AUTO program configuration.
MIX PROGRAM
The MIX program does not work with SUMMER/WINTER program. It is designed to produce heating or
cooling, always
prioritising
the DHW. To
produce
heating the machine needs relay signals (thermostat
signals) at points DI1 and / or DI4 to. To
produce
cooling the heat pump needs relay signals at points
DI3 and / or points DI5.
Note that, to work with the mixed program, the
th-tune terminals cannot be used
implementing the
“buffer
tank” scheme. Also you should pay attention to the “heating stop temperature” in
for
heating and cooling
in user menu (see section 4.5 points 1.3, 1.6 and 1.7).
To set the MIX
program it is necessary to
follow the steps in AUTO program and
to
set a summer
temperature higher than
the
winter one. The machine will be in MIX program when the outdoor
