8.3.2. Programming relay output parameters in regulation mode On1
At work in this mode the regulator can maintain temperature in the established limits, forbid value
of temperature to exceed an admissible maximum limit, forbid value of temperature to fall below an
admissible minimum limit or to form alarm signal at occurrence of such disturbances.
According to the procedure described in Section 7.1, if necessary, it is possible to change the
upper limit of regulation parameter (setting code “25:”) or lower limit of regulation parameter (setting
“24:”), full travel time for actuator valves (setting code“26:L”) and the speed of regulation – pause time
in seconds between the valve opening (closing) of 1% of the full valve runtime (setting code“27:P”).
If value of parameter “27:P” is established equal to zero - at break of conditions the
corresponding relay will be continuously connected (it can be used for alarm signal formation).
To move to menu level (“INT”) press and hold button

8.3.3. Programming relay output parameters in regulation mode On2
This mode of regulation is designed for automatic control of temperature Т1 for maintenance of
the room temperature (setting "24"), depending on the changing of the outdoor temperature (measured by
temperature sensor T3) and of adaptation factor value of building (setting "24").
Recommended value of parameter „25:“ is 15.
Settings "26", "27" set as in the mode On1 (see p. 8.3.2
Only for mode On2 is used:
- parameter „28:“ - for maintenance of accuracy of flow temperature (hysteresis). Recommended
value of maintenance accuracy is 0,5...1 ºC (Reducing its value, frequency of opening/closing of the
valve increases)
- parameter „29:“ - for setting of the maximum admissible limit of flow temperature
Recommended value is 10 ... 20 ° C greater than the possible maximum working flow
temperature.
This parameter is intended to limit the flow temperature at failure of temperature sensor or
erroneous settings case.
8.4. Activating test mode
In test mode it is possible to achieve precise results within short measuring time.
When test mode is activated, calculation process is stopped and the meter readings are saved in
memory. After return to normal mode, the original values from before the test are displayed again.
Test mode is activated by short double pressing configuration button „SET“.“TEST” label is
displayed on the upper part of LCD.
In test mode by shortly pressing button

Volume of liquid can be simulated automatically by the calculator,
Provides automatic verification mode (For definition of measurement error of energy, without
measurement error of flow), when the meter is simulating water quantity and calculate the quantities
of energy, according to the measured temperature (and pressure).
The automatic test mode can be used, when flow sensors are not connected or not filled by water.
Testing time is 100s.
