• Overview
Your device can be controlled by a central control unit through a pilot
wire, in which case the different operating modes will be remotely en-
abled by the programmer.

Frost protection
* Unchangeable factory settings
You can only control the device by pilot wire in the Auto mode. In the
other modes, the orders transmitted by the pilot wire will not be exe-
cuted.
Note: when presence is detected in the room, the device automatically
returns to the initial mode.
In general, a pilot wire control system makes it possible to impose exter-
nally a lowering of the temperature setpoint, combined with the inter-
nal programming and the occupancy detection.
If several lowering requests appear simultaneously, priority is given to
the lowest temperature setpoint, thus maximizing savings (see infor-
mation on priorities for different modes on page 11).
When a signal is sent from the pilot wire, the self learning optimization
function is suspended.
Remarks:
By default, when the sensor is enabled and detects movement in the
room, the display lights up for a few seconds then switches off. To
change the backlight see page 12, backlight setting.

The detection zone is divided
into active and inactive areas.
A person that crosses the area

Active area
• Load shedding
Inactive area
In case of over consumption, an energy power manager or a disconnec-
tor doesn’t trigger a trip of the general circuit-breaker (example: simul-
taneous operating of your various household appliances and others).
This allows you to reduce the energy power subscribed and therefore
optimize your subscription with your energy provider.
IMHOTEP creation controllers are designed to operate with pilot wire
load shedding systems.
Orders sent by the pilot wire are executed by the device’s electronic
controller which will apply the setpoint corresponding to the order sent.
The "Stop" order corresponds to the load shedding. When this order is
received, the device switches to "standby" and then returns to the initial
operating mode.

Side view
Important: Do not use load shedding by a power fail. Unlike
pilot shedding, this type of shedding results in a series of sud-
den and frequent power cuts, which cause premature wear of
the device or even deterioration not covered by the manufac-
turer’s warranty.
Exemption to an order coming from a pilot wire
external programmer
This feature allows you to modify temporarily the setting temperature
until the next order sent by the central control unit or the transition to
00:00.
