2.2.3  Bathroom Switch (Option)

Ventilation with the MTD-ERV 350 can also be op-

erated by means of a bathroom switch.

A  bathroom  switch  can  be  used  to  temporarily 

set  the  highest  ventilation  level  of  the  MTD-ERV

350. This switch can be installed in the bathroom, 

for example, for discharging excess moisture as 

quickly as possible after showering. As the bath-

room  switches  can  have  very  different  designs, 

no switch is illustrated here.

If desired, the user can also enter an activation 

and  deactivation  delay  for  the  bathroom  switch 

via  the  CC  Ease  operating  unit  (see  section 

2.3.7). This allows the user to specify, for exam-

ple, that the MTD-ERV 350 switches to the high-

est ventilation level 5 minutes after the bathroom 

switch is activated and then returns to the normal 

(or  originally  set)  ventilation  level  automatically 

after 20 minutes.

In many cases, however, no separate bathroom 

switch  is  installed  and  the  bathroom  ventilation 

control is integrated into the bathroom light switch. 

The MTD-ERV 350 then switches automatically to 

the  highest  ventilation  level  when  the  bathroom 

light  is  switched  on. The  MTD-ERV 350  then  re-

turns to the normal (or originally set) ventilation 

level  as  soon  as  the  bathroom  light  is  switched 

off. Here again, an activation and deactivation de-
lay can be set via the CCE Ease operating unit.

2.3  Use of the CC Ease Operating Unit

The following functions can be set using the CC Ease 
operating unit:
•  Reading off and setting date and time.

•  Reading off and setting the comfort tempera-

ture.

•  Reading off and setting the ventilation levels.

•  Switching the extractor hood on and off (op-

tion)*.

•  Switching the supply and exhaust air fans on 

and off.

•  Setting an individual ventilation programme.

•  Setting additional ventilation control func-

tions/options in the P menus.

These  functions  are  described  in  more  detail 

briefl y in the following sections.

2.3.1 Setting Date and Time

Via the CC Ease operating unit it is possible:
•  To set the date and time.

Proceed as follows:
1. 

Press

 for two seconds on " 

 " briefl y again to quit the menu.

2.3.2  ReadingandSettingComfort Temperature

Via the CC Ease operating unit it is possible:

v

To read off and set the comfort temperature.

The  comfort  temperature  is  the  temperature  at 

which the MTD-ERV 350:

(a)  Uses the heat exchanger for heat recovery;

(b)  Switches  on  the  bypass  (hence  bypassing 

the heat exchanger) to (temporarily) interrupt the 

exchange  of  heat  between  the  exhaust  air  and 

the supply air.

You  can  read  off  the  comfort  temperature,  but 

also set the desired temperature. The MTD-ERV

350  will  then  automatically  maintain  this  tem-

perature as closely as possible after setting. The 

comfort  temperature  generally  corresponds  to 

the  temperature  that  you  have  set  on  the  room 

thermostat (of your central heating).

Reading off the comfort 
temperature

Proceed as follows:
1.
