STARTING BASIC OPERATION
6.4.1
OPERATING MODE
The regulator has 4 operating modes, depending on the heat pump model: Cool, Heat,
Auto and Manual selection of the operating mode. The available operating mode is controlled
by parameter F29.
F29=0, only Auto mode (C/H).
F29=1, only Heat mode (C/H).
F29=2, only Cool mode (C/H).
F29=3, Manual selection of the operating mode (M).
In the Cool mode, the machine starts cooling when the probe temperature is higher than
the "Temperature se Temperature differential" and it stops cooling when the
temperature is lower than the "Setpoint temperature - Differential temperature".
In the Heat mode, the machine starts heating the water when the probe temperature is
lower than the "Temperature se Temperature differential" and it stops heating when
the temperature is higher than the "Setpoint temperature - Differential temperature".
In the Auto mode, the machine starts cooling when the probe temperature is higher than the
"Temperature se Auto mode temperature differential" and it stops cooling when the
temperature is lower than the "Setpoint temperature". The machine starts heating when the
probe temperature is lower than the "Temperature setpoint - Auto mode temperature
differential" and it stops heating when the temperature is higher than the "Setpoint
temperature".

HEAT MODE
Start-up process:
Start-up conditions: Water intake temperature < (Setpoint temperature - Temperature
differential);
and the Compressor stop time ≥ Compressor delay time.
