Ordering Vysa-Reg™ is simple. Choose the number of channels or heating zones you require. This is normally the number of rooms to be heated.
Vysa-Reg™ uses 3kW rated semi-conductor switches to switch the load in each power channel as standard. For greater loads the capacity can be increased to 5kW per channel if required. For even greater loads, Vysa-Reg™ can control more than one power channel from one sensor if the specification requires but it is unusual for one sensor to control more than one zone or more than one room.
One power channel can be controlled by two sensors. This might be required, for example, when a heating system incorporates floor heating and heating convectors. The floor sensor controls the floor temperature and the air sensor controls room temperature. If either sensor's temperature setting is exceeded the appropriate power channel for floor heating is switched off.
