Programmable Thermostat

Mermaid’s standard Digital Programmable Thermostat. Designed to be used with any Mermaid unit.

Dimensions: 4 1/2″ length x 1 1/4″ width x 3 1/4″ height

Non-Programmable Thermostat

As an alternative to the standard Digital Programmable Thermostat, Mermaid offers a simple Non-Programmable Thermostat that can be mounted vertically or horizontally. It is ideal for applications where programming features will not be necessary.

Simply set the fan to AUTO (comes on with the unit) or ON (continuous duty), and set your desired temperature – and that’s it! The thermostat will now maintain that set temperature until you turn it off or change the temperature. Again, this item is ideal for folks looking for a simple controller and a slimmer wall mount design. This can be a FREE alternative to your Programmable Thermosat upon purchase of any Mermaid Air System.
