2. GENERAL INSTALLATION
2.1 RESIDEO AQUAPUMP VARIABLE SPEED CIRCULATOR
Resideo AquaPUMP auto zone changes the pump speed
according to the system demand without any requirement of
external controls or control wiring.
The Resideo AquaPUMP circulator is recommended for
circulating water in closed hydronic heating systems or
potable water systems.
Models
• PCVF-ECM2020/U cast iron
• PCVF-ECM2020-LF/U stainless steel
The Resideo AquaPUMP includes operating modes suitable
for systems with constant or variable flows, such as:
• Underfloor heating systems
• One-pipe (series) systems
• Two-pipe (parallel) systems
• Multi-zone heating systems
Resideo AquaPUMP circulators incorporate variable speed
control technology with an ECM motor, enabling optimum
energy efficiency and occupant comfort, with built-in control
algorithms that can adapt to continuously changing system
requirements.
The Resideo AquaPUMP features a user-friendly
frontmounted control panel (see section 5) and wiring box for
ease of installation.
2.2 ADVANTAGES OF INSTALLING A RESIDEO AQUAPUMP
VARIABLE SPEED CIRCULATOR
Nine different modes of operation to suit different system
requirements:
• Easily selectable from the front mounted display.
• Modes include sensorless demand-based control, Auto
and proportional pressure, fixed speed and constant
pressure.
• Analog input for external variable speed control.
• Power consumption and flow rate clearly displayed.
• Broad operating range, producing 20 feet of head or 20
USgpm of flow, provides versatility to cover the
performance of a wide range of fixed speed or variable
speed circulators.
• Flange to flange compatibility with many competing
models.
• Front mounted wiring box for ease of installation and
service.
3. INSTALLATION
3.1 EXTRA ELECTRICAL CONNECTOR IN THE BOX
For your convenience Resideo has supplied a PG7 electrical
strain relief connector in the box. It can replace the signal
port plug to secure an insulated signal cable with an outer
diameter between 0.118 and 0.234 inches.
3.2 MOUNTING
All servicing personnel should be equipped with proper
personal protective equipment. Shut off the water supply, or
isolate the pump area. If valves have been installed, on the
suction and discharge sides of the pump, close them. If no
valves have been installed it may be necessary to drain the
system. It is best to leave the drain valve open while working
on the system.
Install suction and discharge flanges on the pipe ends. The
use of Teflon tape sealer or a high quality thread sealant is
recommended. Install the AquaPUMP variable speed
circulator with the flange gaskets. Flange bolts should be
tightened evenly to 60lb-inch of torque. To wire the
AquaPUMP variable speed circulator, follow section 4.0 in the
Electrical Connection section below.
Install the circulator where there will be sufficient room for
inspection and service.
NOTE:
For future servicing, isolation flanges can be used in
place of standard flanges.
