4.5.1 Setpoint Limitations
Setpoint limitations can be controlled through “Allowed Range”, “Minimum Setpoint” and “Maximum
Setpoint” parameters. “Allowed Range” parameter limits setpoint values relative to the default setpoint values
of the operating modes downloaded with ETS when commissioned. “Maximum Setpoint” and “Minimum
Setpoint” values are absolute values limit all operating modes setpoints. If relative setpoint limitation conflict
with absolute limitation, absolute value overwrites the relative value.
“Maximum Setpoint” must be configured as bigger than “Minimum Setpoint” otherwise these parameter
below will be set as minimum and maximum setpoint.
For temperature unit as Celsius (
°C
): Minimum Setpoint = 0
°C, Maximum Setpoint = 40 °C
For temperature unit as Fahrenheit (
°F
): Minimum Setpoint = 32
°F, Maximum Setpoint = 95 °F
4.5.2 Operating Modes
Thermostat has 4 operating modes; these are “Comfort Mode”, “Night Mode”, “Away Mode” and “Protect
Mode”. Transition from one operating mode to another can be achieved through “Operating Mode Button” on
the thermostat or “Operating Mode” communication objects that explained in Thermostat chapter.
Additionally, thermostat regulation can be turned off by pressing the “Operating Mode Button” for longer than
7 seconds or sending off (0) to the “Regulation” communication object. While regulation is off, thermostat will
only send temperature values over “Current Temperature” communication object. Regulation can be restarted
by pressing “Operating Mode Button” or sending on (1) to the “Regulation” communication object.
Comfort, Night, Away Modes
These 3 operating modes have their own predefined setpoint temperatures and, if fan control is used, fan
speeds. When thermostat enters an operating mode, current setpoint temperature will be set as that operating
modes setpoint temperature and if fan control exists, then fan speed will also be set. When setpoint
temperatures or fan speeds for operating modes modified using “Setpoint Buttons”, “Fan Speed Button” or
over respective communication objects, new values overwrites the old values and become the new default
values for the operating mode.
If Comfort, Night and Away modes setpoint temperatures are not compatible to “Minimum Setpoint” and
“Maximum Setpoint” limitations; Comfort, Night and Away mode setpoints sets as closest acceptable values.
Protect Mode
“Protect Mode” differs from other modes by having two setpoint, “Heat Protection Limit” and “Frost Protection
Limit”, when thermostats control mode is heat, setpoint will be set as “Frost Protection Limit” and when
control mode is cool, setpoint will be set as “Heat Protection Limit”.
“Protect Mode” is also the error mode, when error sources (Window Status, Split Heat Error, Split Cool Error)
indicates an error, thermostat will enter “Protect Mode” and will not change its operating mode until error is
fixed. Error state will be shown on the LCD by activating “Warning Icon”.
