t_INTERVAL_C
sets the cooling mode compressor re-start delay. When the compressor stops running, it will not re-start
until at least
t_INTERVAL_C
minutes have elapsed.

HEAT MODE SETTING
In
HEAT MODE SETTING
the following parameters should be
set.
HEAT MODE
enables or disables heating mode.
T1S RANGE
selects the heat pump leaving water set
temperature range that is available to the user for heating mode on the user interface main screen.
LOW
or
HIGH
should
be selected to suit the type of space heating terminals installed. When
LOW
is selected, the maximum set temperature is
55°C. If the climate-related curve function is selected, the curve selected is the low temperature curve. When
HIGH
is
selected, the maximum set temperature is 60°C. If the climate-related curve function is selected, the curve selected is the
high temperature curve. Climate-related curves refer to Part 3, 8.1 “Environment Temperature Curves”.
T4HMAX
sets the ambient temperature above which the heat pump will
not operate in heating mode. The highest value that
T4HMAX
can take is
35°C, which is the heating mode upper ambient temperature operating
limit of the heat pump. Refer to Figure 3-7.20.
T4HMIN
sets the ambient temperature below which the heat pump will not operate in heating mode. The lowest value
that
T4CMIN
can take is -25°C, which is the heating mode lower ambient temperature operating limit of the heat pump.
Refer to Figure 3-7.20.
dT1SH
:
When T1S < 47°C,
dT1SH
sets the temperature difference between the
heat pump leaving water temperature (T1) and the heat pump leaving
water set temperature (T1S) above which the heat pump provides heated
water to the space heating terminals. When T1S – T1 ≥ dT1SH the heat
pump provides heated water to the space heating terminals and when T1 ≥
T1S the heat pump does not provide heated water to the space heating terminals. Refer to Figures 3-7.21.
When T1S ≥ 47°C,
dT1SH
sets the temperature difference between the
heat pump leaving water temperature (T1) and the heat pump leaving
water set temperature (T1S) above which the heat pump provides heated
water to the space heating terminals, unless T1S + dT1SH > 65°C. When
either T1S – T1 ≥ dT1SH or T1 < 65°C the heat pump provides heated
water to the space heating terminals and when T1 ≥ T1S the heat pump
does not provide heated water to the space heating terminals. Refer to Figures 3-7.22.
