Temperature may be maintained via a heat relay or solid state relay drive or 0-10V with H1SO output module plus a cool relay to 0.1o C or F.

Humidity is maintained via one relay, from either a wet & dry temperature sensor system or an electronic humidity sensor. (Not supplied unless specified)

Turn cycle sets number of turns per day and duration .

Ventilation output occurs when extra cooling is needed.
