dT1SC is the temperature difference between T1(actual outlet water
temperature) and T1S(target outlet water temperature) for starting
the unit in cool mode, only when the T1 high enough will the unit turn
on, and the unit will turn off if T1 drop to a certain value. It can be
illustrated in the picture below:.

In the picture ΔT is a parameter relate to ambient temperature, it
can't be changed in the user interface dTSC is the temperature
difference between Ta(actual room temperature) and TS(target room
temperature) for starting the unit when ROOM TEMP. is enabled
in TEMP.TYPE SETTING（refer to field setting/
TEMP.TYPE SETTING）. Only when the Ta high enough
will the unit turn on, and the unit will turn off if Ta drop to a certain
value. It can be illustrated in the picture below(only when room
thermostat is available will this function be available ).

6.10 HEAT MODE SETTING
■ About HEAT MODE SETTING
HEAT MODE SETTING mode typically consists of the following：
1. HEAT MODE: Enable or disable the HEAT mode
2. T1S RANGE: Selecting the range of setting outlet water temperature
3. T4HMAX: Setting the maximum operation ambient temperature
4. T4HMIN: Setting the minimum operation ambient temperature
5. dTISH: Setting the temperature difference for starting the unit
6. t_INTERVAL_H: Setting the compressor start time interval
■ How to set the Heat mode
To determine whether the HEAT mode is effective, go to
MENU> FOR SERVICEMAN> HEAT MODE SETTING.
Press OK. The following page will appear

When the cursor is on HEAT MODE, Using ◄、► to scroll to YES
or NON and press OK to enable or disable the heat mode, When the
cursor is on T1S RANGE, Using ◄、►to scroll to YES or NON and
press OK to select the range of target outlet water temperature.
When LOW is selected, the maximum target temperature is 55℃，if
climate related curve function （correspond to "weather temperature
set" in the user interface）is enabled , the curve selected is low
temperature curve. When HIGH is selected, the maximum target
temperature is 60℃，if climate related curve function （correspond
to "weather temperature set" in the user interface）is enabled , the
curve selected is high temperature curve.
When the cursor is on T4HMAX、T4HMIN、dT1SH、dTSH or
t_INTERVAL_H, Using ◄、►、▼、▲ to scroll and adjust the
parameter.

T4HMAX is the maximum operation ambient temperature for heat
mode. The unit can't work if the ambient temperature above it.
T4HMIN is the minimum operation ambient temperature for heat
mode. the unit will turn off if the ambient temperature below it.
The relationship between the operation of the unit and ambient
temperature can be illustrated in the picture below:

dT1SH is the temperature difference between T1 and T1S for starting
the unit in heat mode.
When the target outlet water temperature T1S<47, the unit will on or
off as described below(∆T is a parameter relate to T1S, which can't
be changed on the user interface):
T1S+dT1SH

When the target outlet water temperature T1S≥47, the unit will on or
off as described below：

dTSH is the temperature difference between Ta(Ta is the room
temperature) and TS for starting the unit when ROOM TEMP. is
enabled in TEMP.TYPE SETTING（refer tofield setting/
TEMP.TYPE SETTING）. Only when Ta drop to a certain value will
the unit turn on, and the unit will turn off if Ta high enough. It can be
illustrated in the picture below(only when room thermostat is
available will this function be available ).

t_INTERVAL_H is the compressor start time interval in heat mode.
When the compressor stops running, the next time that the
compressor turn on should be " t_INTERVAL_H" minute later at least.
6.11 AUTO MODE SETTING
■ About AUTO SETTING
Controlling AUTO mode typically consists of the following：
1. T4AUTOCMIN：setting the minimum operating ambient temperature
for cooling
2.T4AUTOHMAX: setting the maximum operating ambient temperature
for heating
■ How to set the AUTO mode
To determine whether the AUTO mode is effective, go to
MENU> FOR SERVICEMAN> AUTO MODE SETTING. Press OK.
