Product Description
Issue 2017-04-03
Energy storage unit
The “Battery” icon indicates the current state of the energy storage unit of the room control module.
The room control module continuously monitors the charge state of the energy storage unit. The
“Battery” icon appears on the display if the charge state drops below 30%.
NOTE
Charge the energy storage unit by placing the RPW404P-FTL in a source of light for two hours (day
light or artificial light, but not direct sun light).
Energy source
The internal AA lithium batteries support solar operation. The resources of the energy source are only
used when the internal energy storage unit can no longer guarantee the function of the room control
module.
The service life of the AA lithium batteries depends on the transmission frequency, the aging of the
batteries and the self-discharge. They generally last for several years.
NOTE
If the “Battery” icon begins to appear in the display more and more frequently, it indicates that the AA
lithium batteries need to be replaced.
This must be carried out by an authorized service technician.
Please contact your supplier.
Rapid temperature drop
If the room control module detects a rapid drop in temperature (e.g. a window has been opened), the
radio actuator closes the valve for a maximum of 30 minutes.
The “Window” icon appears on the RPW404P-FTL display.
The rapid drop in temperature detected is not included in the learned utilization time profile.
NOTE
Press and hold the “
” button for approx. 5 seconds to end this function early.
Extended absence
The room control module continuously monitors the room utilization. If the room control module
detects a longer absence (three days without occupancy), the utilization time profile permanently
switches to economy mode and the
icon appears on the display.
If the “Occupancy button” is pressed after a longer absence, or if the room control module detects
room occupancy for a period of 20 minutes, the utilization time profile switches to comfort mode and
the learned utilization time profile becomes active again.
Summer mode
Between June 1 and August 31 of a year, the room temperature control switches to summer mode.
Room temperature control is then in economy mode.
The devices only consume a small amount of power.
The “Sun” icon appears and the “Occupancy” icon disappears.
