RegulusRGMAT E G60 LOAD UNIT with UPM 3, insulated
for heating systems

1. Introduction
RegulusRGMAT E G60 Load Unit makes boiler installation quicker as it contains all important
components needed for boiler circuit circulation and boiler protection against low-temperature corrosion.
It is designed to be installed directly on a boiler return piping. The min. distance of the pipe axis from a
wall is 100 mm to enable insulation removal if needed.
This Load Unit is intended for hydronic fireplaces and solid-fuel boilers.
2. RGMAT E G60 Description
RGMAT E G60 keeps the temperature at the boiler inlet above the flue gas condensation temperatures,
which prevents so called low-temperature corrosion of the boiler combustion chamber. This limits con-
densation and boiler tarring significantly, the efficiency of fuel combustion increases and service life of
the boiler is extended.
Main Features
Function maintaining a minimum inlet temperature into a boiler (fireplace) through a load
valve
Application Load Unit for solid-fuel boilers and fireplaces; it prevents low-temperature
corrosion and boiler (fire) fouling

3. RGMAT E G60 Connection Diagram
Install the Load Unit respecting the following instructions:
Connect the boiler inlet piping to the Load Unit outlet marked AB. Connect the return line from the
heating system to the Ainlet, and the outlet pipe from the boiler to the Binlet via a T-piece. Take care
to install shut-off valves and filter where necessary to avoid draining the whole system for valve
cleaning or replacing the thermostatic element.
When the connecting pipes are not arranged or sloped properly, the load valve may get blocked by
air inside. This may hinder or even disable its operation.
Always respect valid rules and boiler manufacturer’s data during installation.
Possible Connection Example I.
The diagram shows a typical connection of a solid-fuel boiler, thermal store and a heating circuit (with
a recommended CSE MIX W pump station - not included in supply). If the boiler is also used for DHW
heating, it is recommended to install also CSE OTS ZV W pump station (not included in supply).
Possible Connection Example II.
The diagram shows a typical connection of a solid-fuel boiler, combination thermal store (permitting
DHW heating) and a heating circuit (with a recommended CSE MIX W pump station - not included in
supply).

4. Function description of a TSV3B valve
TSV3B TSV5B 6/4Mx5/4F load valve is fitted with an
integrated thermostatic insert that will close the Ainlet
(from a heating system), if the return water temperature
to the boiler (AB outlet) is lower than the opening one. As
soon as the opening temperature is reached, the
thermostat starts opening the Ainlet slowly and mixing
the cold return water with the hot water from the boiler
flow (Binlet) with the aim to reach the opening temperature
in the return pipe (AB outlet).
At the same time, the valve closes the Binlet, limiting so
the hot water flow coming from the bypass till its complete
tight closure. Thanks to this, no balancing valve is needed.
The load valve is made of brass, element and plug seals
are in EPDM, cone seal is made of NBR.

Power supply 230 V, 50 Hz
Power consumption (min./max.) 2/42 W
Current (min./max) 0.04/0.40 A
IP rating IP44
Max. speed 5288 rpm
Weighted average power ≤ 20 W
Energy Efficiency Index ≤ 0,20 by EN 16 297/3

Pump control
The circulation pump can be controlled by an external PWM signal
(prole for use in heating systems) or without a PWM signal by
selecting a pump performance curve.
A maximum curve of a pump working range can be dened.
- with PWM signal the pump speed changes with the signal value up to the maximum of the
selected curve
- without PWM signal the pump runs at the max. speed according to the selected curve

6. Installation options
This Load Unit comes in the version for horizontal installation to the right of a boiler. However, it can be
installed also into vertical piping or horizontally to the left of a boiler. When being installed horizontally
to the left of a boiler, the Load Unit needs to be turned by 180° and the TSV3B valve turned as shown
in the pics below.
