After switching the module on and selecting DHCP option, the controller automatically downloads such parameters as IP
address, IP mask, gateway address and DNS address from the local network. If any problems arise when downloading the
network parameters, they may be set manually. The procedure of obtaining these parameters is described in detail in the
instruction manual of the Internet Module.
NOTE
EU L-8 controller may cooperate with the Internet module, which enables the user to view and adjust certain
parameters via the Internet. Such online control is possible only after purchasing and connecting an additional
module ST-507 or WiFi RS.

OPERATION DELAY
3.1.
VOLTAGE-FREE CONTACT
The regulator will enable the voltage-free contact after the pre-defined delay time if any of the zones has not reached the
pre-set temperature (heating - if the temperature is too low; cooling - if the temperature is too high). The controller disables
the contact when the pre-set temperature has been reached.
3.2.
PUMP
L-8 controls the pump operation - it enables the pump after the pre-defined delay time if any of the zones has not reached
the pre-set temperature. When all the zones reach the pre-set temperature, the pump is disabled.
Delay function enables the user to define the delay time for pump activation after the temperature drops below the pre-set
value in any of the zones. Pump activation delay is used to ensure enough time for the actuator to open.
4.
ADDITIONAL CONTACTS
After registering MW-1 module, the following options appear:
Information – the controller screen shows information about the status, operation mode, range and delay time.
ON
Delay time – the regulator enables the contact after the pre-defined delay time if any of the zones has not reached
the pre-set temperature. When all the zones reach the pre-set temperature, the contact is disabled.
Operation mode – this option is used to activate the operation mode as a pump, voltage-free contact or for a given
zone from 1 to 8.
5.
HEATING - COOLING
This function enables the user to select the operation mode:
Heating – all the zones are heated.
Cooling – all the zones are cooled.
Automatic – two-state input from the heat pump. Selecting between heating and cooling.
6.
VALVE REGISTRATION
L-8 may control an additional valve via a valve module (e.g. i-1m). The regulators connect using RS communication but the
registration process is necessary. There is a range of parameters enabling the user to adjust the valve operation to individual
needs.
