Product Usage Instructions
Safety:
Before using the EU-L-10 controller, ensure that it is properly mounted and
clean it if dusty or dirty.
Device Description :
The EU-L-10 controller is designed for controlling thermostatic actuators. It
works in conjunction with room regulators, which provide current temperature
readings from a specific zone. Based on this data, the external controller
manages the thermostatic actuators by opening them when the temperature is too
low and closing them when the pre-set temperature has been reached.
The controller features the following assets:
- Enables the contact after 2 minutes.
NOTE: The regulator is equipped with a WT 6,3A tube fuse-link to protect the network. Do not use a higher amperage fuse as it may damage the controller.
How to Install the Controller:
No installation instructions are provided in the user manual extract.
Maintenance, Technical Data:
Before and during the heating season, it is recommended to check the
condition of the controller’s cables. Additionally, ensure that the controller
is properly mounted and clean it if dusty or dirty.
FAQ:
Q: Can I connect pumps directly to the pump control outputs?
A: No, it is not recommended to connect pumps directly to the pump control
outputs. To avoid damaging the device, an additional safety circuit must be
used between the regulator and the pump. The manufacturer recommends using the
ZP-01 pump adapter, which must be purchased separately.
Q: What are the harmonized standards used for compliance assessment?
A: The harmonized standards used for compliance assessment are PN-EN IEC
60730-2-9:2019-06, PN-EN 60730-1:2016-10, and PN EN IEC 63000:2019-01 RoHS.
The pictures and diagrams are for illustration purposes only. The manufacturer reserves the right to introduce some hanges.
SAFETY
Before using the device for the first time the user should read the following
regulations carefully. Not obeying the rules included in this manual may lead
to personal injuries or controller damage. The user’s manual should be stored
in a safe place for further reference. In order to avoid accidents and errors
it should be ensured that every person using the device has familiarized
themselves with the principle of operation as well as security functions of
the controller. If the device is to be sold or put in a different place, make
sure that the user’s manual is there with the device so that any potential
user has access to essential information about the device.
The manufacturer does not accept responsibility for any injuries or damage
resulting from negligence; therefore, users are obliged to take the necessary
safety measures listed in this manual to protect their lives and property.
WARNING
- High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving the power supply (plugging cables, installing the device etc.).
- The device should be installed by a qualified electrician.
- Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the insulation resistance of the cables.
- The regulator should not be operated by children.
NOTE
- The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply during storm.
- Any use other than specified by the manufacturer is forbidden.
- Before and during the heating season, the controller should be checked for condition of its cables. The user should also check if the controller is properly mounted and clean it if dusty or dirty.
Changes in the merchandise described in the manual may have been introduced subsequent to its completion on September 10th 2018. The manufacturer retains the right to introduce changes to the structure. The illustrations may include additional equipment. Print technology may result in differences in colours shown.
We are committed to protecting the environment. Manufacturing electronic devices imposes an obligation of providing for environmentally safe disposal of used electronic components and devices. Hence, we have been entered into a register kept by the Inspection For Environmental Protection. The crossed-out bin symbol on a product means that the product may not be disposed of to household waste containers. Recycling of wastes helps to protect the environment. The user is obliged to transfer their used equipment to a collection point where all electric and electronic components will be recycled.
DEVICE DESCRIPTION
EU-L-10 controller is intended for controlling thermostatic actuators. It cooperates with room regulators, which send current temperature readings from a given zone. Based on the data, the external controller manages the thermostatic actuators (opening them when the temperature is too low and closing them when the pre-set temperature has been reached).
Controller assets:
- Possibility of controlling the thermostatic actuators with the use of 18 outputs:
- 8 zones / 2 outputs each (in case of a higher number of actuators, the maximum output load is 0,3 A).
- 2 zones / 1 output each (in case of a higher number of actuators, the maximum output load is 0,3 A).
- Possibility of connecting to each zone one dedicated room regulator (EU-R-10b, EU-R-10z, EU-R-10s) or standard two-state regulators (EU-294v1, EU-292v3, EU-295v3).
- One 230 V output for a pump.
- Voltage-free contact (e.g. for controlling the heating device).
- Voltage contact for controlling the floor pump.
- Contact activation delay (for voltage-free and pump output). When the zone temperature is too low, the pump will enable the contact after 2 minutes.
NOTE
The regulator has a WT 6,3A tube fuse-link protecting the network. Higher
amperage fuse should not be used as it may damage the controller.
- Zone icons 1-10
- Icon indicating voltage-free contact and pump operation
- Icon indicating that the controller has been connected to the power supply
WARNING
If pump manufacturer requires an external main switch, power supply fuse or
additional residual current device selective for distorted currents it is
recomemnded not to connect pumps directly to pump control outputs.
To avoid damaging to the device, an additional safety circuit must be used
between the regulator and the pump. The manufacturer recommends the ZP-01 pump
adapter, which must be purchased separately.
HOW TO INSTALL THE CONTROLLER
EU-L-10 should be installed by a qualified person.
WARNING
- Risk of fatal electric shock from touching live connections. Before working on the controller switch off the power supply and prevent it from being accidentally switched on.
- Incorrect connection of cables may lead to controller damage.
MAINTENANCE, TECHNICAL DATA
Before and during the heating season, the controller should be checked for condition of its cables. The user should also check if the controller is properly mounted and clean it if dusty or dirty.
