Purpose
Description of the external panel
Functioning
The RT-825 temperature controller is designed for direct control of
heating devices powered by 230 V with maximum current no higher
than 16 A.
The controller can operate in one of four operating modes:
- operation with an internal temperature sensor
- operation with an external temperature sensor (included)
- operation with two temperature sensors
- operation in "timer” mode
When the room temperature falls below 2°C from the temperature set
in the controller, the heating device switches on (
symbol on the
display). When the room temperature is higher than the set
temperature, the heating device will be disconnected. If the controller
operates in "0" mode, with two external and internal temperature
sensors (parameter F3)
and the temperature in the room exceeds the
Programming
Press the MENU button to enter the programming mode. In the
programming mode you can set 8 parameters. Use the UP/DOWN
buttons to choose one of the parameters. Press ON/OFF button to
edit a parameter. Change the value of the parameter in the para
-
meter edit mode using the UP/DOWN buttons. Confirm setting
with the ON/OFF button.
Parameters
F1 - set the time for automatic switching-on of the controller.
Minimum setting - 1 h.
F2 - set the time for automatic switching-off of the controller.
Minimum setting - 1 h
F3 - set the operating mode for the temperature sensors:
1 - operation with an internal temperature sensor
2 - operation with an external temperature sensor (included)
3 - operation with two temperature sensors (default setting)
F4 - set the time: week, hour, minute
F5 - set the upper threshold of the temperature protection in the
range of 40°C to 70°C with increments of 1°C (factory setting:
50°C). It works only in the mode of operation with two
temperature sensors.
F6 - set the antifreeze protection in the range of 2°C to 10°C with
increments of 1°C (factory setting: 3°C).
F7 - set temperature correction in case there is a difference
between temperature indication from the controller and
actual temperature in room. The correction can be adjusted
within ±5 °C with increments of 0.1 °C.
F8 - set the weekly program of temperature regulation in a room
according to the time of day a
n
d divided into working days,
Saturday and Sunday.
Set the weekly program of controller operation (F8)
Every day in the controller program is divided into four parts
marked with icons:
- morning
- forenoon (leaving the house)
-
afternoon, evening (coming back)
- night
It is necessary to set the start time for each of these periods (the
hour of the end of the given period is the starting time of the next).
The start times for each time of the day should be set separately for
business days, Saturdays and Sundays. Temperature value is
programmed for each time of day.
The following weekly program of the controller operation is set:

value set in parameter F6 (antifreeze mode), the heating device
will be switched on, whether the controller is on or off.
Timer mode operation
The "timer" function operates in a cyclic mode starting from
switching on the controller for the set time (parameter F1), and
then the controller will be switched off for the set time
(parameter F2) etc. on all days of the week. The activation time of
the controller starts when the number of hours is accepted with
the ON/OFF key. When the "timer" function is activated, the
temperature control is maintained depending on the settings.
