•
Attach front cover of controller.
•
Install
TANK
(
T2
) sensor in the bottom port of the storage tank (or where applicable to
the application)
•
Install
SOLAR Collector
(
T1
) sensor into the port provided on the solar manifold on the
HOT outlet end of the manifold. Once installed in the manifold, use a small amount of
silicon to seal the sensor port so the sensor does not register air temperature and can not
fall out. Secure cable to pipework using cable ties or similar.

Turn on controller.

Plug pump into controller
How the controller works/testing
The Novus temperature differential controller provides power to a pump (or similar) when the
pre-programed temperature differences at 2 set points are met. It also has many other functions
that are explained below. This controller has been programed to suit domestic solar hot water
applications. The main settings are:
(dON
) Pump on = When the solar collector is 8 Deg C or more than the tank.
(dOF)
Pump off =
When the solar collector is 4 Deg C or less than the tank.
(ICE)
Pump will turn on when the collector temperature is below 2 Deg C and will pump warm water
from the storage tank up to the collector to protect from damage from frost. The pump will turn off
when the collector reaches 5 Deg C.
(HT1)
This is the maximum temperature (120 Deg C) the collector sensor can register. The pump will
not turn on if above this temperature.
(HT2)
This is the maximum temperature the tank will be heated to. Set to 75 Deg C. Heating a
storage tank above this temperature can damage or shorten the life of the storage tank.
To access the Novus settings>
Hold down the P bottom for until the dON displays. Release the P bottom. You can now adjust these
settings using the up and down bottoms. To access the dOF setting, press the P botton.
All settings should not be changed unless by an experienced technician.
All other settings can be accessed as per the Novus manual. Manual can be found inside the
enclosure.
