Description
RAMSES 714
- Electronic room thermostats for all types of
heating, e.g. gas, water, electric heating etc.
- Individual room control possible in combination
with Theben actuators
- Heating status display via LED
- External temperature reduction (approx.
3.5 K) is possible via control with time switch.
Temperature reduction can be cut to 2 K by
opening a wire bridge
RAMSES 714 A
As RAMSES 714, but:
- External temperature sensor for underfl oor
heating (wet rooms or bathroom heating)
- Switchable for the connection of available
NTC sensors (33 KΩ/25 °C)
- Switch for heating ON/OFF
