Great for:
- Harnessing renewable energy
- Controlling hot water temperature in solar installations e.g. Swimming Pools, Hot Tubs and Hot Water
- Recycling hot air in factories, warehouses and agricultural buildings
- Cooling grain stores to maintain correct differential
- Includes x 2 NTC sensors, N322 model has additional relay output
The N322S is a controller originally intended for solar water heating applications. It controls liquid or air circulation system based on the difference in temperature between the two supplied sensors.
The instrument contains two NTC-type temperature sensors. In a solar application the control output is used for activating the water circulation pump. This maintains an even temperature between the solar collector and storage tank.
For air destratification/circulation the control output is used to activate the high level fan to keep an even temperature throughout the building layers. This eliminates wasted heat trapped at the top of a building.
As part of a solar system it provides protections against overheating and freezing to the piping, preventing damage to the system.
The N322S is also available as a 12-24V model or with optional RS485 communications.
