General Information
These instructions guide you through the installation and operation of
this BritTherm™ circulation pump. The UPS2A Commercial is a high
efficiency circulator which is perfectly suited to operate in:
• Single zone heating systems
• Multi zone heating systems
• Underfloor heating systems
The pump incorporates a permanent magnet motor with differential
pressure control which enables its performance to be aligned with
actual system demand.
It has a connection size of 1½", a maximum head of 8 meters and a port
to port distance of 180mm making it perfect for heavy domestic and
light commercial applications.

Pump Liquid
BritTherm™ pumps require
clean, thin, non-aggressive
liquids to operate correctly and
prevent damage to their internal
components.
The liquids used must not contain
any solid particles, fibres or mineral
oil.
Liquids running through circulation
pumps used on heating systems
must comply with the accepted
standards of quality especially in
domestic applications.
Liquids that do not comply will
void the warranty offered with
the circulation pump.

Pressure Curve
3

Operating Modes
The operating point moves back and forth on the constant
pressure curve according to the volume of flow from the
system.
CP2 to CP5
These 2 speeds are the minimum and maximum in constant
pressure mode. The curve is shown in the graph on the
previous page.
CP1 & CP6
The operating point moves back and forth on the proportion-
al pressure curve according to the volume of flow from the
system. As shown in the graph, the pump pressure is
directly proportional to demand.
PP2 to PP5
These 2 speeds are the minimum and maximum in
proportional pressure mode. The curve is shown in the graph
on the previous page.
PP1 & PP6
PP1 - (Proportional Pressure 1) the duty point moves up/down on the
lowest proportional pressure curve. Head pressure is then reduced and
increased at falling and rising heating demand respectively.
PP2 - (Proportional Pressure 2) the duty point moves up/down on the
highest proportional pressure curve. Head pressure is then reduced and
increased at falling and rising heating demand respectively.
CP1 - (Constant Pressure 1) the duty point of the pump moves out or in
the constant pressure curve depending on heating demand. Head
pressure remains constant irrespective of heating demand.
CP2 - (Constant Pressure 2) the duty point of the pump moves out or in
the constant pressure curve depending on heating demand. Head
pressure remains constant irrespective of heating demand.

Fault Finding
Before starting any work on the pump please ensure
the electricity supply is turned off and cannot be
accidentally switched back on at any time.
Fault Control Panel Cause Remedy
Pump doesn’t
run at all
Light is off A) One fuse
is blown
Replace fuse
Noise in the
system
Lights on for power
and pump setting
A) Air in system Vent the system
Insufficient Lights on for power
and pump setting
A) Pump
performance
is too low
Increase the
suction head
B) Flow is too
high
Reduce the
suction head
Noise in the
pump
Lights on for power
and pump setting
A) Air in pump Let the pump run,
it vents itself
over time
B) Inlet pressure
is too low
Increase the inlet
pressure. Check
the air volume in
the expansion tank
if installed
Only shows power A) Failure of
electricity supply,
might be too low
Check the
supply falls
within the
specified range
B) The current/
voltage operated
circuit breaker
has tripped out
Cut in the
circuit break
C) The pump is
defective
Replace pump
