1.3 Measurements
2.0 Mounting
RAM 797 B should only be installed in dry
rooms!
We recommend mounting the device in the
living-room on an interior wall where the air can
circulate.
Mounting should be made approx. 1.5 m from
the floor.
Press in pins on the lower side of the device
(fig. 2). Remove the base of the control device.
Fix the base carefully to the wall (fig. 3).
Make sure that the contact surface of the base
and the battery case do not get clogged!
Fig. 2

To ensure longevity and proper functioning of the
device, only new alkaline cells of the same
type, namely LR 6 (AA) should be used.
Depending on control and switching frequency,
operating time of time controlled thermostat
RAM 797 B with new batteries amounts to
approx. 12 months. When changing batteries all
data will remain in the memory for approx. 10
min.
Initial installation:
Remove insulating tape from the battery case
(fig. 1/no. 21). Press button for approx 1
sec.
Changing batteries:
1. Open the front lid of the device
2. Observe polarity; insert batteries into the
battery case
3. Close front lid
Device is now functional
Automatic battery control:
1. – If the display shows a blinking
symbol, the alkaline cells need to be
changed within the next 3 – 4 weeks.
2. – If the whole display is blinking, then the time
controlled thermostat switches ON constantly.
Heating is no longer controlled by the
time controlled thermostat!
Turning the blinking display off:
1. Press any button
2. After new batteries are inserted the blinking
stops automatically with the next switching or
on the following day.

2.2 Inserting/changing the battery
Installation and mounting of electrical devices
should only be carried out by a professional elec-
trician. National regulations must be adhered to!

Summer/winter changeover is already program-
med until the year 2039. Choice of 3 different
switching groups (see table below) when restar-
ting (RESET) or during automatic mode.
3.0 Initial service
For setting purposes, open the cover lied of the
device.
3.1 Using the automatic summer/winter
changeover
Due to non-use in the summer months, circulati-
on pumps may become stuck. An included pump
protection program activates the circulation
pump daily at 12.00 for the duration of 1 minute.
The pump protection program is activated by
interrupting the blue wire connection within the
device. Changing the pump protection program is
not possible.
If no settings are made, the device will regulate a
constant temperature of 21° C.
The basic program and the basic regulation set-
tings will not be deleted from the memory.
Warning:
All data stored will be deleted after RESET!
If the device is in the inquiry or programming
mode and no button is pressed, the display will
automatically return to the automatic mode and
adjust to the correct switching mode after
approx. 40 sec.

4.0 Programming
4.1 Basic program
Time controlled thermostat RAM 797 B features
a basic program that permanently remains in the
memory. This basic program heats the living room
as of 6.00 o’clock to 21° C and as of 22.00 the
night program lowers the temperature to 16° C.
After the basic program is deleted and no new
program is entered, the temperature will be con-
stantly regulated at + 6° C.
The display shows the symbol .
4.3 Deleting the basic program
If you did not chose the summer/winter changeo-
ver during initial setup, you can add this at a later
date.
Setting:
Pres buttons and simultaneously. With
button chose the desired summer/winter
changeover switching group (see 3.0). Save by
pressing button .
Confirm the displayed date with button . If
needed, change date with buttons or .

rent temperatures with optional combination of
days for the individual creation of your heating
program.
Example: desired temperature 21° C on Tue and
Wed beginning at 6.30

In the automatic mode you can set a certain con-
stant temperature by pressing buttons and
simultaneously. If the basic setting is not
changed, a constant 21° C will be regulated
independently from the automatic mode.
A change in temperature between 16 and 30° C
can be achieved using buttons or . After
approx. 5 sec. the change is automatically saved
in the program.

Operating Mode:
A one-time certain temperature change can be
set for an individually programmed duration
between 10 min. and 23 hours 50 min. A program
review occurs after completion of the party mode.
Thereafter the device operates according to the
programmed time and temperature standards.
Setting:
in automatic mode press the and buttons
simulatneously. Set the desired duration of the
party mode with or . Approx. 4 sec. after
release of the or button the device
automatically takes on the set time (display:
symbol r+ ).
Set the desired temperature change with the
or button. This entry will also be taken on
after 4 sec. The party mode can be interrupted at
any point in time by pressing the button.

5.0 Remote control by telephone + 21° C
RAM 797 B features a telephone contact.
Terminals 11 + 12 in the base of the device can
be connected to the floating relay contact of a
remote control telephone switch. By signal trans-
mission via telephone you can set the device
directly to „comfort temperature“ mode.
The display shows the symbol .
A constant 21° C will be regulated.
The signal can be cancelled with a new telepho-
ne impulse or manually, depending on the device,
directly on the remote control telephone switch.
Symbol vanishes.
Time controlled thermostat RAM 797 B is equip-
ped with a holiday program. This mode can be set
for the duration of max. 99 days and max. 99
days in advance. During this program the tempe-
rature is set at a constant 16° C. The display
shows the following symbol h.
Example:
Beginning in 2 days at midnight a holiday pro-
gram for the duration of 10 days will start.
4.11 Holiday program h+ 16° C
If the holiday program is to be cancelled, the dis-
play of the holiday program must be reset to
