1 - Description
Regulus LYRA Thermal Stores are intended for accumulation and subsequent distribution of thermal energy from
solid-fuel fired boilers, heat pumps, solar collectors, electric boilers etc. The Thermal Store shall be always connected
to a sealed heating circuit. The tank comes with complete accessories for connection to heating circuits, solar system
and hot water.
The accessories supplied represent a complete solution for connecting a heating system, connecting cold water inlet
for DHW heating and subsequent DHW output. In the recirculation variant this also enables connection of a circulation
pipe. The hot water circulation pump is already integrated in a fresh water station. Heat sources shall be connected to
the free inlets at the tank rear, following the diagrams included in this Manual (Chapter 5.5). When more heat sources
are combined, some intelligent controller should be used to control the heat sources and sinks, incl. the Thermal Store
charging and discharging, for example Regulus IR12 Intelligent Controller.
1.1 - Models
There are 4 models of Regulus LYRA:
- for one heating circuit, no hot water recirculation (code 12231),
- for one heating circuit, with hot water recirculation (code 12229),
- for two heating circuits, no hot water recirculation (code 12230),
- for two heating circuits, with hot water recirculation (code 12228).
1.2 - Tank protection
The inner surface has no finish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal insulation
Thermal insulation is included in the scope of delivery. The insulation consists of 3 layers; the first layer is made of
soft insulation tightly fitting to the tank. The second, main insulation layer, features a coefficient of thermal conductivity
l=0,032 W/m.K. The third layer is represented by a tough, glossy, washable surface. The total insulation thickness is
100 mm.
1.4 - Packaging
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap. Included in the package are all com-
ponents to be fitted on the tank. Insulation is in a separate package.
2 - General Information
This Owners Manual is an integral and important part of the product and must be handed over to the User. Read care-
fully the instructions in this Manual as they contain important information concerning safety, installation, operation and
maintenance. Keep this Manual for later reference. The appliance shall be installed by a qualified person according to
valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate heating water and distribute it subsequently. It shall be connected to a heat-
ing system and heat sources. It is intended also for DHW heating, but exclusively through the enclosed fresh water
station with a plate heat exchanger.
Using the accumulation tank for other purposes than above described (e.g. as a domestic hot water tank) is
forbidden and the manufacturer accepts no responsibility for damage caused by improper or wrong use.
The output of heat sources not equipped with their own safety valve and connected to the tank fitted with the
enclosed safety valve shall never exceed 110 kW.

4 - Operation
This Thermal Store is designed to heat water and accumulate heat for space heating in domestic or industrial
applications, however always in sealed pressure circuits with forced circulation. In the heat store, heating
water is heated up from several heat sources like various types of hot-water boilers, renewable energy sources (heat
pumps, solar collectors), or electric heating elements.

MOUNTING INSTRUCTIONS
WARNING! At least 20 °C and 4 persons are necessary to mount the insulation. All
threaded connections shall be sealed either with a thread sealant or with the gaskets
included in separate kits.
1. Remove the tank from its pallet and place it to its approximate position, shift the
bottom insulation under the tank.
2. Slide the insulation inserts into the openings for connections.
3. Fit on the front insulation part, then the rear insulation part.
Check the proper position of the insulation towards the
sockets prior to final fixing. Use the jig to close the locks.
│8
4. Peel off the protective foil from the insulation, apply the self-adhesive annuluses
around the openings for connections. Some annuluses are cut out, these shall be
used in places where openings are close to each other (the annuluses overlap).
5. Fit the assembly with elbow ball valve (code 12690). From this point
on, it is important to stick to the sequence of installation steps
described below!
6. Fit the assembly with ball valve and pressure gauge (code 12689).
7. Do hrdla 1“ pod skupinu s manometrem namontovat zátku (kód 7691).
9 │
8. Fit the 3/4” ball valve (code 998) to the tank and the 3/4” FF hex nipple (code 6970) into
the valve, both these components are included in the Kit code 13234. Turn the ball valve
into the position shown in the fig.
9. Fit the ball valve and elbow assembly (code 13236) into the lower 1“ opening.
10. Align the metal sheet against the four pins and fix it using 4 screws M6x16 with washers
(codes 12996 and 7853) - both these components are included in the Kit code 12226.
Do not forget to place insulation washers under the metal sheet and loosen the clamps.
Fit the pump station with 4-way mixing valves (code 12224 or 12225). Using a 5/4” union
nut, connect it with the angled valve assembly mounted earlier (see point 5). Tighten the
clamps.

11. Fit the fresh water station (code either 9717 or 9913) using 4 screws M6x16
with washers (codes 12996 and 7853) - all these components are included in the Kit
code 12226.
12. Connect the TSV3B assembly (code 12687) using a 3/4“ pipe, 100 mm long (code
11946) - included in Kit 13234 with 3/4“ ball valve - see point 8.
13. Connect the TSV3B assembly with the DHW assembly..
