4.3 Pump Output
There are 2 outputs:
•
Live contact output (230Vac)
•
Free contact output
These outputs can be used to trigger:
•
A zone valve
•
A pump
•
A boiler or heat pump
The 2 outputs are triggered when there are a heating or
cooling demand
•
In the controller if DIP switch 1=local
•
In the system if DIP switch 1=Global
The delay between the heating or cooling demand and the
pump activation is configurable.
•
Pump starts 2 minutes after heating or cooling
demand if DIP switch 3=OFF
•
Pump starts 5 minutes after heating or cooling
demand if DIP switch 3=ON
The purpose it to take account the latency of the actuator.
The delay between the end of the heating or cooling
demand and pump output stop is configurable:
•
Pump stops 5 minutes after heating or cooling
demand stop if DIP switch 3=OFF
•
Pump stops 20 minutes after heating or
cooling demand stop if DIP switch 3=ON
The purpose is to dispel the energy.
4.4 Security input
This is a security input (Free contact).
Closed Contact
No security detection
Opened Contact
Overheating or
overcooling detection
When the contact is opened,
•
The local pump output is stopped
•
The actuators are closed
•
The Pump/Drier Led is red blinking
•
The Heat and Cool led is Red or blue
blinking
•
If the controller is a sub controller, the
heating or cooling demand is not sent to
the main controller
You can use a contact thermostat for thermal security. You
can install 2 contact thermostats in serial to protect against
both overheating and overcooling.
The product is delivered with a strap on the connector.
