REGOMAT PUMP STATION
- for boilers and fireplaces
Instruction Manual

1. Introduction
REGOMAT Pump Station makes boiler installation quicker as it contains all important
components needed for boiler protection. It is designed to be installed directly on a
boiler incoming pipe or on a wall. The distance between the pipe axis and wall shall
be at least 100 mm to enable insulation removal.
This pump station is intended for solid-fuel boilers and fireplaces.
2.
Description
Regomat keeps the return temperature to a boiler (fireplace) at or above the valve
opening temperature, which prevents low-temperature corrosion and boiler fouling.
This prevents condensation and boiler tarring. The boiler then works with higher
efficiency and its service life is extended.

4. Possible installation positions with a boiler
This pump station comes in the version for horizontal installation on the left
side of a boiler. However, it can be installed also into a vertical piping or on the
right side of a boiler. When being installed horizontally on the right side of a
boiler, the pump station needs to be turned by 180° and the TVS valve turned
as shown in the pics. below.

6. Function description of TSV3B valve
TSV B thermostatic mixing valve is fitted with an
integrated thermostatic insert that will close the “A”
inlet (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 “A” inlet slowly and mixing the cold
return water with the hot water from the “B” inlet
(boiler outlet) so that the return nominal
temperature (“AB” outlet) is reached. At the same
time, it closes the “B“ inlet, limiting so the hot water
flow coming from the by-pass till its complete tight
closure. Thanks to this, no balancing valve is
needed. The Thermostatic mixing valve is made of
brass, sealing of the element and body plug are
made of EPDM, sealing of closing plug is made of
NBR.

Pump control
The pump can be controlled by an external PWM signal (profile 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 defined.
- 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

Setting selection for UPM3
1. Pr
ess the pushbutton until the LEDs start flashing, the pump will switch
to adjustment selection mode.
2. To select
your desired setting, press the button repeatedly until you find the setting
you need, see the pics below. If you pass the desired setting, you have to go one
more round until it appears again – there is no way back in the loop.

3. Release the button for more than 10 s and the LEDs will return to “performance
view”, while the last setting is saved.
