Heating mode
About Heating mode
HEAT MODE SETTING typically consists of the following:
•
HEAT MODE: Enable or disable the HEATING mode
•
T1S RANGE: Selecting the range of target outlet water
temperature
•
T4HMAX: Setting the maximum ambient operating
temperature
• T4HMIN: Setting the minimum operating ambient
operating temperature
• dTISH: Setting the temperature difference for starting the
unit
• 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 be displayed:
When the cursor is on HEAT MODE, use UP DOWN to scroll
to YES or NON and press OK to enable or disable the heat
mode.
When the cursor is on the T1S RANGE, use UP DOWN to
scroll to YES or NON and press OK to select the range of
outlet water temperature.
When LOW is selected, the maximum target temperature is
55°C.
If climate-related curve function (corresponds 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°C.
If climate-related curve function (corresponds 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, use LEFT RIGHT and UP DOWN to scroll
and adjust the parameter.
T4HMAX is the maximum ambient operating temperature for
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 turn on or off as described below :
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 (see chapter
Start-up and configuration - TEMP.TYPE SETTING).
Only when Ta drops to a certain value will the unit turn on,
and the unit will turn off if the Ta high enough.
See diagram below.
(only when ROOM TEMP is enabled 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 turns on should be “
t_INTERVAL_H” and one minute later at least.
heat mode.
The unit will not work if the ambient temperature is higher.
T4HMIN is the minimum ambient operating temperature for
heat mode.
The unit will turn off if the ambient temperature is lower.
The relationship between the operation of the unit and
ambient temperature can be seen in the picture below:
