2.70 THP VS Pump Family
IS3206VSP3 Rev-A
4.10.
Remote Control Wiring/Operation
The 2.70 THP VS pump family can be controlled in a wide variety of ways as described below:
1.
They can operate by themselves in Stand-Alone Mode using their built-in programmable timers.
2.
They can also be controlled from third party controls (i.e. another manufacturer’s control) and Hayward controls
that are not software compatible using relay contacts. See section 5.3 for more information regarding connecting
this pump and third party/non-software compatible Hayward controls.
3.
They can communicate with and be controlled by Hayward pool and spa controls. See section 5.4 for more
information regarding connecting this pump and Hayward pool and spa controls.

SVRS Notes (Only applicable to SVRS pump models)
The Safety Vacuum Release System (SVRS) model is designed to provide an additional layer of protection against
body suction entrapment. It complies with
ASME/ANSI A112.19.17-2002 SVRS
standard.
1.
SVRS devices shall only be installed in conjunction with an
ASME A112.19.8
suction fitting, or a 12 in. x 12 in.
(305 mm x 305 mm) drain grate or larger, or an approved channel drain at each suction outlet or drain outlet.
2.
Check valves and hydrostatic valves shall not be used in suction systems protected by SVRS devices.
WARNING
– The presence of a hydrostatic valve in the suction piping has been shown to prolong the high
vacuum present at the drain, even though the drain was protected by an SVRS device.
3.
All SVRS devices shall be factory set or field adjusted to site-specific hydraulic conditions. Once installed, the
system shall be tested by simulating an entrapment event.
4.
A ball, butterfly, or sliding gate valve shall be installed within 2 ft. (0.6 m) upstream from the SVRS (between the
SVRS and the protected suction outlet), or a test mat shall be used to cover the suction outlet to simulate an
entrapment event. There shall be three simulated entrapment tests conducted to verify proper adjustment and
operation of the device.
5.
One SVRS device shall be installed for each circulating pump plumbed directly to the suction outlet(s) without
the use of valves that could isolate the SVRS device from the suction system.
4.12.
Digital Control Interface Orientation
The Digital Control Interface can be rotated to any of four desired positions after installation by loosening the two
screws securing the user interface to the motor drive, lifting the user interface and rotating it to the desired position,
and tightening the two screws in the new position.
