DESCRIPTION
PT32 is an intelligent digital room thermostat with a backlit display. Its advantages involve a quick change
in the desired temperature by simply turning the wheel, and possibility of setting up to 9 weekly programs
with 6 temperature changes per day.
INSTALLATION AND LOCATION
Install the thermostat at a suitable place where its operation cannot be affected by direct flow of hot air
from the heater, sunshine or other disturbing effects. Do not install it on an external wall either. The instal-
lation height should be approx. 1.5 m above the floor. Place the thermostat in the “reference room”, such
as the living room (the heating source will switch according to the temperature in this room).
The installation must only be done by a properly qualified person!
Before installation, disconnect the power supply!
1) Switch off the main circuit breaker.
2) Remove the control part from the lower cover of the device (Fig.1, page 3).
3) Chip away the central plastic piece from the lower cover to lead in conductors.
4) Run the conductor through the hole and connect it to the terminal acc. to the diagram.
5) Fasten the lower cover to the wiring box with screws (Fig. 2, page 3).
6) Batteries are located at the back of the control part. Remove their protective paper (on first use), or
insert new batteries (follow the instructions on page 3).
7) Mount the control part on the lower cover.
8) Switch on the main circuit breaker and test correct connection of the thermostat, see
page.9 (TEST).
9) Upon first start (or reset), the thermostat displays “SET CLOCK”, set the current time and date
according to page 4. After that select language see page 6.

MAXIMUM CONTROL TEMP.
Selection of regulation type:
PI = proportional-integral control
The PI-control principle consists in comparison of the cur-
rent room temperature with its desired value.
The PI-control aims at achieving and maintaining
the desired temperature without overshooting
(see the graph). For correct function of the PI-control,
set the control parameters according to the type of
the heating system with respect the room thermal
inertia; see CONST 6.
Note: If the PI-control is selected, CONST 5 is skipped
automatically.

HS = hysteresis
Difference between the desired and current temperature.
If the hysteresis is 1 °C and the desired temperature is 20 °C, the ther-
mostat switches off at 20 °C, and on at 19 °C (see the graph).
For correct hysteresis function, set the parameters according to the
heating system type; see CONST 5.
Note: If hysteresis is selected, CONST 6 is skipped automatically.

The optimum setting is within the range of 10 to 15 min.
The adjustable range is 5 min to 20 min (by 1min).
Set the interval by turning the “ “ and confirm “ “.
Select within the range of 1 to 5 minut. The setting is
determined by the heating system type, and depends on
the PI-control time period selection. Setting according to
the table is recommended.
Set the value by turning the “ “ and confirm “ “.
This value determines the temperature at which the PI-control
starts functioning. For example, the desired temperature is
22 °C, the proportional band is 1.5 °C. Up to 20.5 °C, the
source heats fully. When this value is reached, the PI-control
starts. The PROPORTIONAL band can be set within the ran-
ge of 0.5 to 3.0 °C (by 0.1 °C).
Set the PI band by turning the “ “ and confirm “ “.
Here you can set the minimum switch-on time of the boiler
in minutes at hysteresis. Select within the range
from 1 to 5 minutes according to the type of
the heating system used (see the table).
Set from 0.1 to 6 °C. According to the value preset, the
thermostat switches on at the temperature:

This function provides for the desired temperature at the desired time.
You do not need to consider when to switch on the heating to be
warm when getting up in the morning without heating up long before
uselessly. You just program the time when you want the desired tem-
perature. In two days’ operation, the thermostat ascertains thermal
constants of the room, and then switches the heating in advance as
necessary. The preliminary switch-on time is limited to 2 hours.
PRELIMINARY START OF HEATING
Choose YES/NO by turning the“ “ and confirm “ “.
(factory setting of NO)
