sets whether space heating/cooling modes are controlled according to the room temperature detected by
the temperature sensor in the M-Thermal Mono user interface. If
YES
is selected, the user is able to set the room
temperature set temperature on the user interface’s main screen.
If
YES
is selected for both
WATER FLOW TEMP.
and
ROOM TEMP.
, the user is able to set both the M-Thermal Mono unit’s
leaving water temperature set temperature and the room temperature set temperature on the user interface’s main
screen. (In this situation, on the main screen
►
can be used to move to the room temperature setting).
If
YES
is selected and space heating/cooling modes are controlled according to both the M-Thermal Mono unit’s leaving
water and the room temperature setting, the M-Thermal Mono provides space heating/cooling until both the leaving
water temperature and room temperature conditions are met. Refer to Part 3, 7.5 “COOL MODE SETTING Menu” and Part
3, 7.6 “HEAT MODE SETTING Menu”.

ROOM THERMOSTAT
As an alternative to controlling space heating/cooling modes according the
M-Thermal Mono unit’s leaving water temperature and/or the room temperature
detected by the temperature sensor in the M-Thermal Mono user interface,
separate room thermostat can be installed and used to control space
heating/cooling modes.
In
ROOM THERMOSTAT
the following parameters should be set.
ROOM THERMOSTAT
sets whether or not room thermostats are installed. For installations with room thermostats, select
YES
. For installations without room thermostats, select
NON
.
MODE SETTING
sets whether the room thermostat is to be able to control the heat pump’s mode (space heating or space
cooling). Select
YES
for installations with room thermostats that have mode-control capability. Select
NON
for installations
with room thermostats that do not have mode-control capability. When
YES
is selected, the heat pump’s operating mode is
controlled by the room thermostat and not by the M-Thermal Mono user interface.
DUAL ROOM THERMOSTAT
sets whether the dual room thermostat is available. In
DUAL ROOM,
if
YES
is selected, the
ROOM THERMOSTAT
,
MODE SETTING
