Domestic Heating Circulators
UPP15-50 PumpPlan
Grundfos UPP15-50 PumpPlan is a revolutionary type of domestic
pump system that eliminates the need for traditional two or
three port motorised valves in central heating installations. Pump
Plan integrates two independent pump heads and separate wiring
centre which is connected to the boiler and controls (programmer
and thermostats), enabling PumpPlan to simultaneously circulate
water around the heating and primary hot water systems.
In addition, each pump head can be set to operate individually at
different speed settings, allowing the installer to select the correct
flow and pressure for each part of the system as required.

INSTALLATION
Ensure that the pump shaft is horizontal, which reduces the thrust
bearing load and ensures positive air purging from both the rotor
chamber and impeller housing.
Air must be prevented from entering the unit by incorporating an
effective air vent before the pump. This will avoid air locking of the
pump, with resultant loss of performance.
The shaft must not fall below the horizontal plane, even by a few
degrees, as this causes premature wear of the top bearing and shaft.
Pump Plan should not be installed with the shaft in a vertical plane,
as this may lead to dry running of the top bearing, noise and possible
failure.
In systems where all the flow can be stopped while the pump is
running, e.g. in systems fitted with thermostatic radiator valves, a
by-pass should be fitted between the heating flow and return pipes to
ensure a minimum flow rate through the boiler and pump as required
by the boiler manufacturer.

Before installing the pump, the system should be thoroughly flushed out
to clear all foreign matter such as solder, steel wool, copper filings. We
recommend that the system is cleaned out in accordance with British
Standard 5449 Part 1 1990. The manufacturers guarantee may be
affected if the system has not been flushed of all impurities.
The electrical connection should be carried out by an authorised
electrician in accordance with local regulations.
To avoid cavitation noise and risk of damage to the bearings, the
minimum inldet pressure should be 0.5m at 82°C and 2.8m at 90°C
APPLICATION
The package contains: a 2-circuit pump where one pump head is used
for CH (Central Heating) one pump head is used for HW (Hot Water)
and a dedicated wiring centre for connecting mains and wires from
pumps, room, cylinder and frost stats, boiler and programmer. The pump
can be used in both closed and open systems. Pump overun is automatically
achieved by a relay in the wiring centre.
3/4” BSPM accessory port blanking plug is provided.

The pump is available in a version with three speeds.
The terminal box is easily accessible and has functional cable
connecting terminals. The cable entry is tight and has a built-in cable
relief. The cable entry can be pushed out of its guide to facilitate the
correct fitting of the cable.
Voltage: 1 x 230 V, 50 Hz.
Enclosure class: IP 44.
Insulation class: H.
Cable connection: PG 11.
The pump motor is impedance-protected and consequently
short-circuit-proof. It requires no motor protection.
WIRING CENTRE
Based on signals from the programmer or time clock, cylinder, room and
frost stats, the wiring centre turns the boiler, the HW and the CH pumps
on and off. If the boiler requires pump overrun, the HW pump will be run
on via the a relay and the signal from the boiler P/L terminal.
The wiring centre is CE-marked and conforms with the standards
EN 60 730-2-10 and EN 60 335-1.
Cover, bottom and cable relief are made of composite material ABS. The
wiring centre is mounted on a wall by means of three screws and plugs
supplied with it

Room Stat
1. The Pump Plan wiring centre can also be
used with 2 wire Chronotherm
programmable room stats having volt free
contacts (’VFC’s’).
2. Two wires only are normally required
between the wiring centre and the room
stat. Where the room stat incorporates a
heater resistor the neutral terminal should
be used for improved response of the room
stat.
NOTE: If Room Thermostat is not being
used, link terminals C and NO at the
ROOM STAT connector block
Cylinder Stat
Only two wires are needed between the
cylinder stat and the wiring centre, and
should be connected to ’C’ and ’NO’ as per
the wiring diagram.if a third wire is connected, this may be wired into ’N’
providing the
above diagram is followed. Incorrect
wiring of the cylinder stat will cause the
fuse to blow.
Boiler Connections
Terminals ’L’ and ’N’ provide a permanent
240V supply to the boiler.
Terminal ’S/L’ is a switched live output to
the boiler, asking for the boiler to fire.
The ’P/L’ terminal, when made live by the
boiler pump over run controls, causes the
hot water pump to run regardless of hot
water cylinder demand, to dissipate
boiler heat.
Programmer
If using a HW-CH programmer instead of
a basic time clock, remove the link
between terminals ’HW on’ and ’CH on’ in
the wiring centre.
IMPORTANT:Before connecting a live power supply to
the Wiring Centre it is important to check
that:
The programmer/timeclock receives its
power supply direct from the Wiring
Centre*.
The boiler receives its power supply direct
from the Wiring Centre*
If the thermostat requires a 240V power
supply, this must be supplied direct from
the Wiring Centre*.
If a 240V powered thermostat is used it
must be connected to the C and NO
terminal (there must not be a connection
between C and N, as this will cause the
fuse to blow).
*Providing an external power supply to
The programmer, timeclock or
thermostats will cause damage to the
wiring centre.
