Essential Info

Use the Intermatic RC4G Air Switch Button for Gunite Spas as part of the Air Switch Kit to control one piece of equipment with an air button. The switch can safely control loads without electricity at the pool, spa, or tub side. For example, a pump, air blower, heater, or light can be turned on or off from the side of the pool without risk of electric shock. The tubing is run from the air button to the air control. When the air button is pushed, a blast of air travels through the tubing and engages the air control.

What is Gunite? - Gunite is a mixture of cement and sand sprayed onto contoured and supported surfaces to build a pool. Gunite is mixed and pumped to the site dry, and water is added at the point of application. Plaster or pebble is usually applied over the gunite.

    Had a local pool service company come in and repair my system. They installed something other than an RC4G. It was garbage! Ordered this replacement, installed in seconds, works better than the old one.
