The optimal comfort with minimal energy consumption is guaranteed by the
selection of an individual temperature profile for each day provided by the time
program. In the wireless room thermostat three different time programs can be
selected and customized.
The temperature setpoint should be automatically lowered by 3 K (factory
settings) in reduced mode or lifted in cooling mode. The display shows the
symbol .
In addition, it is possible to connect an external time switch to the input "Eco".
The signal of this time switch reduces the setpoint of the wireless room ther-
mostats also by 3 K or more when active.
Cooling can be activated through an external signal from e.g. a heat pump or
an external switch. For this function two inputs are available: "C/O" and the
"hot" input "24 ... 230 V TB/C/O". In addition it is possible to provide a signal to
a cooling unit with the potential free output C/O.
Depending on the configuration of the wireless room thermostat, the cooling
mode can be activated with the wireless room thermostat with master function,
or with any wireless room thermostat.
To prevent blocking of the pump and valves, once per week the anti-blocking
function is activated. The function is started when one of the outputs was not
active for a week. In this anti-blocking function, the pump is turned on for
3 minutes. The actuators are controlled per channel and will be switched on
for 20 minutes. The pump and the actuators run independently without war-
ning.
When the radio signal between the wireless room thermostat and the wireless
connection module is lost for more than 30 minutes, then the addressed
channels switch over into emergency mode. During the emergency mode the
thermal actuators are in a 30%-on / 70%-off mode of the standard time. The
standard time is determined by the selected control algorithm. The channel
LED(s) is (are) blinking. A warning symbol is shown on the display of the
wireless room thermostat indicating that the emergency function is active. For
a proper functioning of the emergency mode the wireless connection module
must be provided with power not be destroyed by external influences such as
a lightning strike.
The wireless room thermostat measures the room temperature. The tempera-
ture setpoint is specified via the wireless room thermostat. Every 10 minutes
the measured room temperature setpoint and the actual temperature are
transmitted to the wireless connection module. After a change of the setpoint
the new setpoint and the actual value are sent immediately to the wireless
connection module.
For an efficient temperature control, three different control algorithms and an
optimized thermal actuator control are available. For the temperature control
one can select between one on/off and two PWM control algorithms.
With the on / off control the heating will be switched on or off when the tem-
perature difference is greater than 0.5 K. If the setpoint is higher than the
measured temperature, the valves are opened. If the setpoint5 is lower than
the measured temperature, the valves are closed.
