 three core (with protective wire),
 in accordance with applicable
regulations.
Diagram of electrical connections is
presented in Drawing 12. The connection
wires should not have contact with surfaces
of room temperature exceeding the nominal
temperature of their operation.
Terminals L, N and number 1-8 are intended
only for connecting devices with mains
supply 230V~.
Terminals 9-20 are intended for cooperation
with low voltage devices (below 12 V).
Connecting mains supply 230V~ to
terminals 9-10 will damage the
regulator and creates risk of an
electric shock.
Tips of the connected wires, especially power
leads, must be secured against splitting by
means of insulated clamp sleeves, in
accordance with the drawing below:
Drawing 11. Securing wire tips: a) right, b) wrong
The feeder cable should be connected to the
terminals marked with an arrow.
Drawing 12. Diagram of electric connections with
external devices,
where: T1 – boiler temperature sensors (type CT4), T2 –
hot utility water temperature sensors (type CT4), T3 –
emission temperature sensors (type CT2s), T – room
thermostat, DZT-1 – additional thermal safeguard (type
DZT-1 85°C or 90°C), RS232/RS485 – converter, BUS –
connector for digital communication with a computer
(optional) , 1 – mains fuse in the regulator, 2 – mains
switch in the regulator, 3 – protective terminals PE, 4 –
metal enclosure of the regulator, MAINS – mains lead,
STB – safety temperature limiter,
The following isolations are used in the
regulator:
 electronic for fan output, terminals 1-
2 (action type 2.Y in accordance with
PN-EN 60730-1), does not provide
safe isolation – despite isolation on
terminals, dangerous voltage can
occur!
 micro-insulation for central heating
and hot utility water pumps‟ outputs,
terminals 6-6 and 7-8 (action type
2.B in accordance with PN-EN 60730-
1),
11.5 Protective connections
Protective leads should be connected to
terminal marked with .
