B.4. DIMENSIONS
Note: The dimensional diagram of the open load unit is rotated for illustrative purposes, the
outlets for the thermal store connection are mutually aligned (see side view).
C. LOAD UNIT INSTALLATION
The load unit is designed for wall mounting. It shall be mounted in the selected position using
the enclosed installation kit. Choose the right installation height that will enable comfortable
handling the controller. Two mounting holes in the sheet metal in the rear section of the
insulation are used for wall mounting, see dimension diagram below.
Note: In the basic version, the thermal store is supposed to be connected on the left side of
the load unit. If necessary, the load unit can be converted to be connected to a thermal store
on the right side. The conversion procedure is described on the following page.
installation openings
for wall mounting

│8
Procedure for conversion of the load unit to connect the thermal store from
the right
1Remove the top part of insulation. 2
Loosen the nut and remove the extension
for the outlet to the thermal store (this
will be used in step 8).
3
On the right and left side of the insulation
body there are insulated passage points
for connecting the thermal store; take
out the insulation pieces from both the
passage points.
4Loosen the nut and turn the elbow to
the right.
5
Take out the insulation piece for the
boiler pump. Loosen the nuts at both the
discharge and suction ports of the pump
so that you can easily handle the pump.
6Move the pump to the side to allow free
access to the elbow.

9 │
7Loosen the elbow and take it out of the
load unit. 8
Assemble the elbow with the extension
removed in step 3 and re-install it to
same location so that the outlet now
points to the right.
9
Mount the pump back to its original
place, tighten both nuts and return back
the pump insulation piece.
10 Replace all the remaining pieces of
insulation to their original places.
11 The load unit should now look like this. 12 Reinstall the top part of the insulation.

C.1. HYDRAULIC CONNECTION OF THE LOAD UNIT
HOW TO PROCEED:
Make hydraulic connections of the boiler, heating system, thermal store(s) or hot water
tank(s) with the load unit, respecting the selected hydraulic variant (see the following pages)
→ Fill and air bleed the system → Perform a pressure test → Place temperature sensors to
the respective sheaths depending on the selected hydraulic variant → Mount the outdoor
temperature sensor on a north-facing wall about 1.5-3m
above the ground.
HOW TO CONNECT PIPING
The load unit has two side outlets from ball valves for
connecting optional accessories (plugged) from ball valves
11, which are connected with the boiler remain connected
with the boiler even when the ball valves are closed.
Before starting operation, make sure all ball valves
are in the open position (the open/closed position on ball
valves inside the load unit is shown by the groove position).

D. ACCESSORY INSTALLATION
If you do not intend to install any accessories, proceed directly to the controller settings.
INSTRUCTIONS FOR ELECTRICAL WIRING AND ACCESSORY SETTINGS
Electrical wiring of the accessories must be carried out by a person qualied according to the
applicable standards and regulations.
Safety warning
Before working on the unit, switch off the power supply and secure it against being
switched on again! The controller is not equipped with a mains switch. To switch
the unit off, either unplug the power cord from a power outlet, or use a circuit
breaker. Check for the absence of power! Do not use the controller if the housing
shows visible damage.
General instructions for connecting accessories
Low-voltage cables such as temperature sensor cables must be routed separately
from mains voltage cables. Connect temperature sensor cables only to the left-
hand side of the controller, and mains voltage cables and relay cables only to its
right-hand side.
The cables being connected to the unit must not be stripped by more than 55 mm,
and the cable jacket must reach into the housing to the other side of the grommet.
How to proceed:
Accessory cables are connected to free terminals S1 or R3 (see photo below) or CAN
according to the wiring diagram of the selected accessory.
1. Unplug the power cord from the power outlet before starting work.
2. Remove the top section of the load unit insulation and release the controller from the
insulation piece so that you have clear access to the controller. Unscrew the front cover of
the controller.
3. Remove the outer insulation of the cable (in the length of 55 mm max.), run it through the
opening in the rear part of the controller and fit the cable clamp.
4. Strip the last 8-9 mm of all cable cores.
5. Open the connectors with a flat-blade screwdriver and connect the wires according to the
appropriate diagram
6. Close the controller and screw the cover back.
7. Plug the power cord into a power socket and put the controller into operation.
8. Run commissioning of TRS6K BIOMIX controller following the setup wizard and then set the
desired accessories in the controller menu following instructions in the chapter Accessory
Installation.
