Weather-Based Control - Tech Controllers EU-i-2 Plus OT User Manual

regulator function: 'Standard regulator' or 'Tech regulator Algorithm' (this step is necessary to ensure proper
operation of the regulator). Follow the same steps while registering another regulator.
NOTE
It is possible to register up to 3 dedicated regulators to the controller. A
cooperate with additional modules I-1 ( it only supports built-in valves).

Room regulator functions:
1. Closing - when the room regulator reports that the room temperature is too low, the valve starts closing (to
reach the minimum valve opening).
2 Room regulator temperature lower - when the regulator reports that the pre-set room temperature has been
reached, the pre-set valve temperature will change by the value of 'Room reg. temp. lower' parameter (pre-set
temperature - pre-set reduction temperature).
3. Pump deactivation - when the room regulator reports that the pre-set room temperature has been reached,
the circuit pump will be disabled.

WEATHER-BASED CONTROL

For the function of weather control to be active, the external sensor mustn't be exposed to sunlight or influenced by the
weather conditions. After it has been installed in an appropriate place, <weather control> function needs to be activated
in the controller menu.
For the valve to operate correctly, the user defines the pre-set
temperature (downstream of the valve) for 4 intermediate
external temperatures: -20ºC, -10ºC, 0ºC and 10ºC.
In order to configure the pre-set temperature value, touch and
drag appropriate points up or down (the pre-set valve
temperature will be displayed on the left), or use arrows to select
the temperature value. Subsequently, the display will show the
heating curve.
