BPT37
WIRELESS ROOM THERMOSTAT
BPT37 offers you a variety of applications for temperature control in households, offices or workshops.
The transmitting unit features comfortable and simple control. The large, well-arranged display informs
you about every current state of the thermostat. Thermal comfort is guaranteed by the possibility of ad-
justing constants (control system) for various heat sources to economize heating power consumption as
much as possible. The new code self-learning system ensures trouble-free operation with high interference
immunity. The wireless version enables easy and quick installation; there is no need for complicated and
tedious installation of the line between the thermostat and boiler involving floor penetration.

THERMOSTAT LOCATION
We recommend that the installation be done by a person with suitable qualifications in electrical engineering!
Incompetent interference or damage voids the guarantee for the product!
1. Switch off the main circuit breaker.
2. Connect the boiler to the potential-free contact outputs (use the room thermostat
terminals – 2 wires).
3. Connect the receiver to the 230 V/ 50 Hz mains.
4. Switch on the main circuit breaker; the green diode lights up on the receiver; the receiver
is ready for operation.
CODE LEARNING (use if the receiver memory has been erased – the red diode blinks):
1, Press the receiver’s “FUNCTION BUTTON” for about 1.5 sec; the yellow and red LEDs start blinking
alternately; and the receiver awaits the code (“learning mode”).
2, Push the “TEST” button on the receiver; the signal sending sign appears on the display.
3, Receipt of the code in the receiver is indicated by simultaneous blinking of the yellow and red diodes;
thus the code has been learnt.
4, After receipt of the code, the output relay is switched several times to verify the correct functioning
of BPT37.
TESTING CORRECT CONNECTION:
On completion of the installation, test the correct connection by pushing the button on
the transmitter.
The boiler will be tested automatically. It switches ON and OFF several times, and the ,
sign appears on the transmitter display; the orange diode on the receiver indicates that the
relay is closed.

The transmitter must be located as far from interference sources (TV, PC, etc.) as possible; it must not be
placed on a metal base.
For its location, take the thermal properties of the place into account. Owing to bad signal reception,
install the receiver as far from large metal objects as possible (at least 0.5 m).
The receiver is functional immediately after connection to 230 V/ 50 Hz – the GREEN LED lights up.
The output switching contact is galvanically isolated from the control unit.
During installation, make sure that no heavy-current lines run along the thermostat.

14. PROGRAM VERSION
This constant cannot be set, it just informs you about the program ver-
sion.

11
EXTERNAL SENSOR CONNECTION
No external sensor is connected; after connection to the heating system, the
thermostat measures the room temperature with the internal sensor.
In this case, CONST10 is not set!
Once the external sensor is connected to the connector (page 3), perform
RESET (by simply pushing the RESET button). Verify correct connection of
the sensor:: CONST10 has the CI:d2 message and the sign. How-
ever, do not set the temperature with CONST10!
The temperature is measured with an external sensor. The advantage is that you can
measure the temperature in a different room from that in which the thermostat is located
(regulation of water, floor temperature, technological processes, etc.). With CONST2
(page 8), you can set a different maximum temperature within the range 15 to 99.5 °C.
Note: After disconnecting the external sensor, you must perform RESET again; thus you
re-activate the internal sensor.
You can choose the following functions of the BPT37 thermostat:
- regulation by the temperature measured by the internal sensor of the thermostat
- regulation by the temperature measured by the external sensor of the thermostat
- regulation by the temperature measured by the internal sensor with correction of the maximum
temperature of the thermostat external sensor (floor heating)
1, Function – internal sensor
2, Function – external sensor
BPT37 monitors the maximum floor temperature and simultaneously controls the room temperature. The
thermostat (with PI regulation) regulates the room temperature by the internal sensor (standard ther-
mostat function).
- Connect the external sensor (see page 3), which monitors the maximum
floor temperature.
- Perform RESET, the Ci:d2 message and sign appears with CONST10
(indicating correct connection).
- with CONST10 set the maximum floor temperature at which the
thermostat should switch off. If the room temperature reaches the
maximum permitted value, the heating device is switched off even if the
measured room temperature has not reached the required value. When
the external sensor temperature drops by 0.5 °C, the heating device is
switched on again.
It is necessary to set the maximum external sensor temperature (see CONST10, page 9).
To ascertain the current temperature of the internal and external sensor,
you can use the button; the display consecutively shows Cld:LO 1
(for internal sensor temperature) or Cld:LO 2 (external sensor tempera-
ture).

The PI regulation principle consists in a comparison of the current room
temperature with the required one. The CONST 6 option: when setting the
time interval, you must heed the room thermal inertia. The optimum value is 10-
15 minutes. However, if the room temperature fluctuates often, we recommend
you choose a short time interval. The proportional band defines the value at which
the PI regulation starts (CONST 8).
PI REGULATION FUNCTION (CONST 6, 7, 8) EXPLANATION
The PZT (preliminary heating start) function ensures the required tem-
perature at the required time.
Within two days of operation, BPT37 ascertains the room temperature con-
stants, and then automatically switches the heating in advance as necessary.
The preliminary switching time is limited to 2 hours.

Hysteresis
Difference between the required and actual temperature.
The hysteresis can be set from 0.1 to 1.5 °C. If the hysteresis is 1 °C and the re-
quired temperature is 20 °C, the thermostat switches off at 20 °C, and switches
on again at 19 °C (see the graph).
