Control of heating circuit 2
For control of heating circuit 2 the Akva Lux II VX3 (ECL 310) is supplied
with a 2-way valve VS 2 and an electrical actuator AMV 150, which
in combination with the ECL controller controls the heating circuit.
The electrical actuator has undergone a functional test from factory.
In case of operating disturbances the actuator can be closed manu-
ally turning the manual override knob on top of actuator counter-
clockwise.
Please see enclosed instructions,

Circulation pumps, heating circuits
See chapter 13 on page 32 for more information about circulation
pumps.
Safety thermostat
The heating circuit is supplied with a safety thermostat, type AT
pipe thermostat, for protection against overheating.
The AT pipe thermostat is used to regulate the medium tempera-
ture in the pipe, on which the thermostat is mounted. AT senses
the temperature in the pipe through its contact surface and is
therefore suitable to control the flow temperature, as it - in combi-
nation with the ECL controller - switches of the pump to prevent
excessive levels of temperature.
Please see enclosed operating instructions

Akva Lux II VX3
Application
The AT pipe thermostat is used to regulate the
medium temperature in the pipe on which the
thermostat is mounted. AT senses the tempera-
ture in the pipe through its contact surface and is
therefore suitable to control boiler or flow tem-
perature in central heating systems.
The AT pipe thermostat comprises a bimetallaic
sensor, a contact system and a setting knob.
On connection to terminals CO and NC the ther-
mostat breaks on a rise in temperature.
On connection to terminals CO and NO the ther-
mostat close on a rise in temperature.
The AT thermostat can be mounted on the pipe
without emptying the plant of water.

Note!
Temperature range for the safety thermostat is 30 - 90 °C.
The temperature is not preset from factory.
For floor heating the value must be set to max. 50 °C.
In case of radiator heating the value must be set to 80 °C.
