5 Changing system setup
Go to Advanced Settings if necessary to reconfigure initial setup options and
change some other default system setup options as desired.
Changing the basic configurations of the thermostat is to select either
Conventional or Heat pump and adjust the basic heating/cooling settings for the
selected equipment type.
To change the basic configurations
1. From the Home screen, tap , tap and then tap .
2. If prompted, enter the administrator password.
3. Tap and then tap .
4. Tap OK to stop all of the thermostat’s applications. The thermostat restarts.
5. After the restart is completed, tap Equipment and then tap Adapt.
6. Select the equipment type that you want to change settings for.
7. If Conventional is selected, change the heating/cooling stage value or fan
operation condition as desired (you can decide if the fan operates when
heating is energized).
8. If Heat pump is selected, change the following as needed:
– Heating/cooling stage value.
– Reversing valve’s operating condition. You can decide to energize the
reversing valve for heating or cooling.
– Auxiliary heating stage and operation condition. Two auxiliary heating
stages are available. Once you’ve selected one stage, you can decide if the
auxiliary heating device is allowed during heat pump operation. Normally,
when the heat pump is running, an auxiliary electrical heating system is
allowed but an auxiliary gas heating system is not.
NOTE: Refer to the following part to configure some other relevant advanced
settings.
By changing extended configurations, you can:
● Change input assignments. Before any reconfigurations or changes to another
input, it is strongly recommended corresponding peripheral devices be
connected to terminal X1 or X2. The input can be:
– Room temperature
– Operating mode switch
The thermostat switches to the OFF mode if the input is configured as
Normally open. For example, if a thermostat in a hotel is configured to
Normally open for this input, when a hotel guest pulls out the room card, it
activates Normally open. The thermostat switches to the OFF mode. Once
the room card is inserted again, the thermostat restarts the previously
running mode.
If the X1 or X2 input is assigned as Operating mode switch and
configured as Normally open but physically terminal X1/X2 is not
connected with any corresponding peripheral devices, the thermostat may
switch to the OFF mode in the end and refuse to function normally unless
you change to another input.
– Universal contact. A sensor can be associated with X1, X2 as a universal
contact (binary input), e.g. a window detection sensor. By default, this input
is configured as Normally open. With the binary input from the universal
contact, a notification can be shown in the mobile application:
- If configured as Normally open: notification if connection status is
closed. If the status switches to open, the notification disappears.
