1 Principle of operation
The programmable temperature controller T-87IF allows
programming switching events (up to 9) and temperatures
according to personal needs. After installation the device auto-
matically shows the time of day and the room temperature. In
AUTO mode, the heater will be automatically activated accor-
ding to programmed time and temperature. Program 1 is the
default pre-set program (see 8.).
Room temperature will be controlled, the floor temperature will
be limited (measured by the remote sensor). The heater will be
switched on when the temperature drops below the current
set-point.
In case of function „Min Floor Temp“ (H3) it will be heated if the
floor temp drops below the set min-value. This is even when the
room temp. is too high.
In case of function „Max Floor Temp“ (H3) heating will be stop-
ped if the floor temp exceeds the set max-value. This is even
when the room temp. is too low.
2 Installation
Caution!
This device must be installed by a qualified electrician,
according to the wiring diagram on the device and in com-
pliance with all applicable safety regulations.
Appropriate installation measures must be taken to achieve
the requirements of protection class II.
This device, is used to control the temperature only in
dry rooms, under normal environmental conditions. This
electronic device conforms to EN 60730, It is an “indepen-
dently mounted control” and works according to operating
principle 1C.
3 Use
The electronic Room Temperature Controller T-87IF can be used
to control the room temperature in conjunction with:
• Electrical floor heating systems where the floor temperature
has to be limited to a certain value
• Hot-water floor heating systems in conjunction with
thermal actuators
In order to measure the floor temperature the remote
sensor has to be used

8. Pre-set programs
There are 3 pre-set time/temperature programs in the controller.
Pre-set program 1 (as shown below) is the default. Therefore, if
pre-set program 1 is the best program to suit the application,
there will be no need to change the time/temperature settings
on the device.
To select another program see 9. G1.

Notes for Programming
• Activated settings terminate automatically 3 Min after the last
key press, without saving. They return to the mode which was
active before entering the settings, e.g. AUTO, MAN, etc.
• Entering a Code: change value with
+ –
key then press OK
• When going through User- or Installer settings the item num-
ber used in the manual will be displayed, e.g. G1 for „Program
select one“ or H2 for „Control Mode“.
• There may be gaps in the sequence of menu numbers.
Troubleshooting
1. It is getting warm too late:
a. Are clock and program events set correctly?
b. Is the Optimum Start feature switched on? see H7
Did the controller have enough time (several days) to
adapt to the room’s characteristics?
c. Is an automatic change between Summer- and Winter
time activated, see G5
2. The controller does not accept any changes
Is access protection switched on? see G6
3. The range of temperature setting is limited.
Are temperature limits set? See G7
4. Temperature display doesn‘t change.
Is display of set-temperature activated? See G10
5. The room heats up too slow
The floor temperature may be limited from the
controller‘s max-limiter. See H3
6. The room becomes too warm
The floor temperature may be limited from the
controller‘s Min-limiter. See H3
• Min- and max limits for floor temperature adjustable
• Valve protection
• Adaptation to valves normally open or normally closed
• Adjustable heating interrupt according standard EN 50559
(not for valves normally open)
Electric connection
Caution:
disconnect electric circuit from supply
Connecting according to Wiring Diagram
For flexible or solid wires 1 - 2,5 mm2
Connecting the remote sensor
The T-87IF needs a remote temperature sensor. This sensor
should be mounted in such a way that the temperature which
has to be controlled, can be measured correctly. Lay sensor insi-
de a protective tube (simplifies replacement). The sensor lead
can be extended up to 50 m by using a cable and connections
suitable for 230 V. Avoid laying sensor cable alongside power
cables, for example inside a conduit.
Caution!
The sensor is at mains voltage.
