Installation and Operation Manual
IMPORTANT!
Before starting work the installer should carefully read this
Installation & Operation Manual, and ensure all instructions are
observed and understood.
The Solar controller should be mounted, operated and
maintained by trained personnel only. Individuals in training are
only allowed to install the product under the supervision of a
qualified installer.
Instructions in this Installation & Operation manual must be
observed when working with the controller. Incorrect operation
shall render the warrenty void. WATTS shall not be liable in the
case of improper usage. Any modifications or alterations are
not allowed for safety reasons. The Solar controller
maintenance may only be performed by service centres
approved by WATTS.
The functionality of the controller is dependant upon the model
and ancillary equipment. This installation leaflet is part of the
product and has to be kept and maintained with the controller.
APPLICATION
The Solar controller is developed for a Solar heating system.
The temperature of the tank water is controlled by temperature
difference “dt” between the solar collector and tank.
The controller is normally used in conjunction with a solar
station which includes a circulation pump and mechanical
pressure Safety valve.
The controller has been designed for use in dry environments,
e.g. in residential rooms, office spaces and industrial facilities.
Verify that the installation complies with local regulations
before operation.
SAFETY INSTRUCTIONS
Before starting work disconnect power supply!
All installation and wiring work related to the controller must be
carried out only when de-energized. The appliance should be
connected and commissioned by qualified personnel only.
Make sure to adhere to local electrical safety regulations.
The controllers are neither splash- nor drip-proof. Therefore,
they must be located in a dry environment.
Do not interchange the connections of the sensors and the
230V connections under any circumstances! Interchanging
these connections may result in life endangering electrical
hazards or the destruction of the unit and other connected
sensors and appliances.

Basic system, with 1 tank, 1 pump, 1 collectors array and 2
sensors.
With this system you can add extra functions with 1 or 2
sensors (Thermostat, Cooling, Antistagnation, Booster or
Diffcontrol function).
The loading of the tank1 is activated if the temperature
difference “dt” between the collector (T1) and the tank1 (T2) is
sufficient.
2.3.2 System 2
System with 2 tanks, 1 pump, 1 valve, 1 collectors array and
3 sensors. With this system you can add an extra function
with 1 sensor (Thermostat, Cooling, Antistagnation or

The loading of the tanks is activated if the temperature
difference “dt” between the collector (T1) and the tanks (T2,
T4) is sufficient.
You will have different adjustments to define the priority of the
tank and also the loading function for the secondary tank.
These following parameters are available for tsytems with
2 tanks.
Priority Tank
“No Prio”
No priority is done on the tanks. The two tanks are loaded
independently; the only condition is that the “dt” value is
sufficient to initiate tank loading.
“1”
The primary tank will be the tank1 managed by the sensor T2.
It will be named with a small number “1” in the tank on the
main screen.
“2”
The primary tank will be the tank2 managed by the sensor T4.
It will be named with a small number “1” in the tank on the
main screen.
If a primary tank is chosen, the loading of this tank will be
made in priority, the secondary tank will be only loaded if:
- The primary tank will reach the “Maxtemp tank(x)” value
adjusted on “setting” menu.
- If the collector temperature is too small to initiate tank
loading of the primary tank. In this case the secondary tank will
be loaded with the cycle function defined by the two following
parameters. This function allows switch back from second tank
to the priority tank.
(1 cycle = “Prio Time break” + “Prio Time charge”)
Note:
All the time if the “dtMax tank(x)” value of the primary tank
becomes sufficient the loading will switch to the primary tank.
Prio Time charge
Load time duration (ON time) for the cycle function.
- To change the duration press (►) to highlight the line and
select your choice with (+) or (-). (Adjustable to 1 to 30min with

2.4 Outputs configuration
- This menu allows configuration of the specific type of output
and the settings of the device connected to all outputs on the
controller. (E.g.High efficiency or standard pump; with or
without speed control, power relay...etc).
There is also the possibility of using the “free” outputs for an
extra function (Thermostat, Cooling, diffcontrol, antistagnation,
booster...)
Note: The outputs “free”, will be marked “not used”
2.4.1 P1
Main pump output, this output is always used to manage the
solar circuit.
There will be the choice between, High efficiency PWM pump,
standard pump or power relay when large pumps are required.
To change the selected pump press (►) to highlight the line
and select your choice with (+) or (-).
PWM Pump
If a PWM pump is connected, there will be the choice between
the 3 main brands, GRUNDFOS, WILO and LAING.
The speed regulation is done by PWM control "ViH = ~11VDC
ViL = <0,5V VDC" with a signal frequency ~ 250Hz”.
Example of compatibility:
- GRUNDFOS SOLAR PM type.
- WILO STRATOS type.
- LAING ECOCIRC E4 PWM1 type.
It is possible to select in percentage form the minimum and
maximum speed of the pump. (Adjustable from 0 to 100%)
The speed of the pump is variable when the value of dt is
between the range “dtFs” and “dtMin”.
dtFS => dT scale of speed variation.
Speed control of the pumps enables the maximisation of the
energy yield from the collectors.
PWM speed regulation explanation:
Standard Pump
If a standard pump is connected, it is possible to control the
speed of the pump; in this case the speed control is done by
pulse packet function.
It is possible to choose in percent form the minimum and
maximum speed of the pump. (Adjustable 30 to 100%)
The speed of the pump is variable when the value of the dt is
between the range “dtFs” and “dtMin”.
This function is an alternative to the High efficiency pump
(PWM), if it is necessary to optimize the efficiency of the solar
installation a PWM high efficiency pump should be utilized.
If the speed control function is not required, selelct “No Sc” as
choice.
Pulse packet speed regulation explained
Important Note:
As the speed control is done by pulse packet, noise can occur
in the hydraulic circuit, check the compatibility of the hydraulic
circuit (fitting, pipe…) before selecting this form of speed
control.

The controller has the ability to record and store all data and
parameters of the installation on an SD card. This enables the
analysis of the efficiency of the solar installation and also
allows the pre-configuration of the installation parameters on
your computer. (This functions require a special Watts Data
Logger Kit with software. Watts order number P04189)
After the SD card is inserted, it must be activated:
Select the SD card line with (+) or (-) and press (►) to highlight
this line. Now with (+) or (-) you can activate or deactivate the
