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
•
See 3.3
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
See 3.3
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
See 3.3
The purpose is to dispel the energy.
4.4 Security input
This is a security input (Free contact).
Closed Contact

• 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.
No security detection
