10. How to switch off the thermostat
When switched off, the programmable thermostat no longer controls the room tem-
perature and the room is not heated. The display will show OFF, and the buttons will
not function.
In the installer options (see Installation Guide 3.2) you can select whether or not frost
protection will be activated when the thermostat is in OFF state (heating if tempera-
ture falls below 5°C).
Switching OFF
Press button + and – simultaneously for 5 sec. -> OFF will be displayed
Switching ON
Press button + and – simultaneously for 5 sec. -> OFF disappears
II. Installation Guide
Note: The transmission frequency used in this control is used extensively in Europe, for
similar applications. The transmitting power is very low. It is far below the power of a
mobile telephone. Moreover, the transmitter is activated only every 10 minutes The
transmission quality is enhanced by employing special test procedures and repeating
transmissions. Transmitter and receiver are tuned to each other by making use of the
“learning mode”.
1. Applications:
The electronic room thermostat INSTAT+ 868-r can be used for temperature control togeth-
er with:
• Actuators of floor heating systems or radiators
• Oil and gas warm water heating
• Circulating pumps
• Heat pumps
• Electric radiators
An INSTAT 868-a.... radio receiver is required for operation.
2. Installation:
Installation location:
The device should be installed in a location in the room which:
• is easily accessible for operation
• is free from curtains, cupboards, shelves etc.
• enables free air circulation
• is free from direct sun light influence
• is free from draughts (e.g. opening of windows and doors)
• is not affected directly by heat sources
• is not located on an external wall
• is located approx. 1,5 m above floor level
• allows safe radio transmission
• is not in the vicinity of eg. a radio receiver, a television set or a radio transmitter
• is not in the vicinity of metal parts eg. metal doors, metal cupboards, mirrors or steel
reinforced concrete
• if unsure, check radio transmission before installation
(see receiver instructions, section “Radio range test”), look for suitable position if
necessary.
Installation of the thermostat directly onto the wall.
1. Remove battery cover using a coin, then remove batteries.
2. Remove the front cover using a flat screwdriver and separate from back plate.
3. Mount the back plate to a suitable location using suitable wall plugs and screws.
4. Replace the front cover by pushing it fully onto the back plate.
5. Install the 2 AA batteries provided.
6. Reattach the battery cover.
Once mounting has been carried out, the radio links must be established.
see 2.1 oe 2.2
Then the thermostat is ready to work and will automatically start to control the room
temperature according to the pre-set program 1 (refer to User Guide).
All important functions were pre-set in the factory. If you wish to change any of the
settings, please refer to the options in the User Guide section 9.

Note:
In some rare cases it may not be possible to establish a permanent radio link
between the radio transmitter and the radio receiver. We therefore recom-
mend that the reliability of operation at the specific location be checked. In
order to establish longer transmission distances (up to 90 m) or in case of
critical locations, the RF repeater INSTAT 868-rep can be used.
This thermostat can be used in all EU and EFTA countries.

3.4 Low and high limit set points (option 4, 5, table 2)
These limits can be used to prevent temperatures from being set too high or too low.
The set point default values are 32 °C (high limit) and 5 °C (low limit).
3.5 Optimum start (option 6, table 2)
If this function is activated, the thermostat will automatically calculate the warm up
time for the heating system in order to achieve the desired temperature for each
event.
This function is a major energy saving factor.
Note: This function is only possible in the AUTO mode.
After commissioning, it takes a couple of days for the thermostat to gather enough
information to correctly calculate this function.
3.6 Heating/cooling (option 7, table 2)
Use this function to select whether the thermostat is used exclusively for either heat-
ing or cooling applications.
HEATING: The receiver will switch on when the temperature falls below the set point.
COOLING: The receiver will switch on when the temperature rises above the set point.
Note: The same time/temperature events will be used as in heating
3.7 Valve protection (option 9, table 2)
If valve protection is selected, the receiver's relay will be switched on once a day at
10:00 h.
This function is designed to prevent the valves and pumps from seizing during the sum-
mer months.
For electric heating systems or in cases where seizing' is not expected, this feature
should be switched off.
The valve protection time can be set here between OFF and 1...5 minutes
