The default value is 3 (30 minutes). To exit the programming mode turn off the ignition or wait
for 30 seconds after the last press on the programming button was made.
The value of this option is ignored if the module is controlled via the status external control
input №11 (pink/black). The module remains activated until the signal is present at the
input, but for no longer than 120 minutes.
Auxiliary heater mode
In this mode an aftermarket self-contained heater operates according to the algorithms of an
OEM auxiliary engine heater: if the ambient temperature is below 5°С, the module will autmatically
switch into the auxiliary heating mode. If the ambient temperature rises above 12 °C, the heater
will switche off automatically.
To activate/deactivate the auxiliary heating mode switch the vehicle's ignition ON and press the
programming button 12 times (a standard button or the built-in one). The module shall indicate
the option №12 "Auxiliary heater mode" status (refer to the table 3 "System setup") as follows:
•
1 LED flash – the auxiliary heater mode is ON;
•
2 LED flashes – the auxiliary heater mode OFF (the default value).
W‑BUS/Eberspächer protocol selection
In most cases, the protocol is assigned automatically when you connect the system to a heater.
Manual selection of the protocol is required in exceptional cases. Programming is performed only
by the built-in button (see Figure 2). In order to select a protocol switche the ignition on, press the
programming button 6 times. The module shall inform about the item status by series of flashes:
•
1 signal – protocol is not set (factory settings).
•
2 signals – W-BUS.
•
3 signals – Eberspächer
•
4 signals
–
control is disabled.
Change item status by pressing the programming button as many times as it is required. The
module exits programming mode in 15 seconds after the last button-pressing. Upon successful
saving of settings, the LED would flash 4 times; 1 long flash means an error.
