It has a built-in modules that controls the heat sources and pump (by volt-free relay). The control box allows to control 8 different zones. It is equipped with 24V AC voltage outputs actuators. Pluggable terminal blocks provide quick and convenient wiring connections. The control box is designed to work with NC (normally-closed) type actuators. Product compliance This product complies with the essential requirements and other relevant provisions of the following EU Directives: EMC 2014/30/EU, Low Voltage Directive LVD 2014/35/EU, RoHS directive 2011/65/EU. Safety information Use in accordance with national and EU regulations. Device is intended for indoor use only in dry conditions. Product for indoor use only. Installation must be carried out by a qualified person in accordance to national and EU regulations. Before attempting to setup and install, make sure that control box is not connected to any power source. Installation must be carried out by a qualified person. Incorrect installation may cause damage to the wiring centre. The control box should not be installed in areas where it may be exposed to water or damp conditions. PLEASE NOTE: For the entire installation, there may be additional protection requirements, which the installer is responsible for maintaining.

Fuse Please note: Replacement of the fuse to be carried out only when the control box is disconnected from power supply (24 V ~). Main fuse is located under the housing cover next to power supply terminals and secures the control box and the devices connected to it. Use ceramic tube slow blow 250 V ROHS fuses (5x20 mm) with nominal max current 10A. To replace fuse remove the fuse holder with a flat screwdriver and pull out the fuse. Pump output (volt free) The PUMP OUTPUT is a potential-free output (COM/NO) controlling a circulating pump in the heating system, with a maximum load of 6A. The output is short-circuited (the pump starts) always after 3 minutes from the receipt of the heating signal from any controller connected to this control box. The output is switched off (the pump stops) when none of the controllers sends the heating signal. PUMP OUTPUT NO COM max 6A L AC 230V N PE NO COM PUMP OUTPUT When the Pump/Valve control output is activated, the pump status LED shows a constant green light. Boiler control output (volt free) The boiler control output is supported by a relay with voltage-free contacts (NO / COM / NC output). The boiler must be connected to the COM-NO or COM-NC contacts. It is a typical two-state relay. In most cases, the NC terminal is not used. If the thermostats connected to the wiring centre send a signal for heating, the BOILER output contacts activate the relay with a 3-minute delay, allowing the boiler to be turned on. The boiler is turned off immediately, when none of the zones sends a signal for heating.

Maximum current load for each zone is designed to handle up to 6 actuators with a power of 2W each. With more actuators in one zone, an additional relay should be used to make sure that actuators output will be not overloaded.
