Trend IQ204 Controller

Trend IQ204/UNB/24VAC Rationalisation

Recently the Trend portfolio has been reviewed with the addition of new products, whilst also being streamlined with the withdrawal of older product families.

We have taken a final opportunity to buy stock of the Trend IQ204/UNB/24VAC to support our customers. We anticipate a high demand and would like to offer the opportunity to Airedale customers to place critical orders.

Trend have developed a replacement to the IQ204, the Trend IQ4E, but this is NOT a direct replacement, it is anticipated to be a much higher cost and would require additional engineering time for each replacement.

Below is a visual comparison of the replacement Trend IQ4E controller that Airedale will continue to provide for Spare’s replacements.
