Electric Operators
Receive mode: Commands from the controller to the actuator Notes
rx time: max. 1 s ■ The bidirectional data transfer from the wireless partner
to the wireless small actuator must be completely fin-
ished within a maximum time window of 1 s.
DB_3: Valve set point 0 to 100%, linear n=0 to 100 ■ The temperature value (setpoint) or control value is
Temperature set point 0 °C to 40 °C / transferred here from the external wireless partner.
32 °F to 104 °F, linear n= 255 to 0 Which information is sent to the actuator is defined by
DB_1.BIT_2.
DB_2: Temperature actual from RCU 0 °C to ■ The current temperature value (actual value) or control
40 °C / 32 °F to 104 °F , n=255 to 0 value is transferred here from the external wireless
Room controller unit partner.
Which information is sent to the actuator is defined by
DB_1.BIT_2.
DB_1.BIT_7: Run init sequence ■ A “Set zero point” service function is stored here. This
function needs a suitable wireless partner that supports
the function.
DB_1.BIT_6: Lift set ■ Not applicable for MAC-WSA
The service function “Learn stroke” is here. However, it
requires a suitable wireless partner that supports the
function.
DB_1.BIT_5: Valve open ■ A “Forced OPEN” service function is stored here.
However, it requires a suitable wireless partner that sup-
ports the function.
DB_1.BIT_4: Valve closed ■ A “Forced CLOSED” service function is stored here.
However, it requires a suitable wireless partner that sup-
ports the function.
DB_1.BIT_3: Summer bit, reduction of energy consumption ■ The “summer function” is stored in this BIT and is
transferred to the actuator.
If the “summer bit” is transferred from the wireless part-
ner, the communication cycle is extended from 10 min-
utes to 30 minutes. This reduces the energy consump-
tion of the actuator during phases in which no heating
occurs and has a positive effect on the service life of the
batteries. The function must be supported by an external
wireless partner of the actuator and can be optionally
set.
DB_1.BIT_2 Set point selection DB_3 ■ Here you specify whether the temperature measurement
0b0 set point 0 to 100%, value or the actuating signal is made available to the
0b1 temperature set point 0°C to 40°C / wireless actuator as an input signal.
32 °F to 122 °F
DB_1.BIT_1 Set point inverse ■ The inversion of the actuating signal is possible with
this BIT.
DB_1.BIT_0 Select function 0b0 RCU ■ You use this BIT to specify whether the actuator should
0b1 service on operate in normal mode (RCU) or service mode (service
on). However, it requires a suitable wireless partner that
supports this function.
