Functioning Principle
GROHE F-digital is a wireless controlled thermostatic mixer
with wax cartridge. Water flow and temperature can be
changed and set using the Digital Controller and Diverter.
Application
Safe limitation of the maximum outlet temperature is achieved
via pre-set temperature limits which can be changed using the
Digital Controller. There is a protective user operated override
(set at default 38 °C) and a maximum system temperature (set
at default 46 °C).
The product is preassembled.

The buttons of the digital controller/diverter are now
inoperative for 3 minutes.
Fit lid and fasten with screw (A), see Fig. [4].
Priming of pump
The pump cannot be allowed to run dry and the functional
unit will stop this by switching off the functional unit and
flashing green. Therefore, in cases of water supply
below 0.01 MPa / 1m head), assistance to the priming of the
pump may be necessary.
The simplest way to achieve this is by applying suction to the
outlet of the functional unit by:
- Using a hand-operated suction pump on the shower hose,
or
- Sucking on the shower hose.
Where a head shower is fitted, this should first be removed
and a suitable length of rubber hose temporarily fitted.
If the above does not work, the following should be checked
before re-attempting the application of suction:
- Make sure that the inlet check valves are not sticking
(remove temporarily).
Once the system is running, temperature setting should be
varied between hot and cold several times so as to help clear
any air pockets from both inlet sides.
The functional unit must be adapted to the local
conditions, see section Selection menu of the digital
controller, F2 - Calibration.
Settings in the event of a power failure/when changing
batteries
No settings saved by the user will be lost when changing the
batteries or in the event of an interruption of the power supply
