3. SELECT PRESSURE RELIEF (BYPASS)

Barometric bypass works to relief excess pressure in most zoning applications and is the most cost effective solution.  Modulating or "STATIC PRESSURE" Controlled bypass can be used for more accurate and quieter pressure relief.

Outdoor Air Thermostat
Sale Price: $59.99 Original Price: $79.99

The Outdoor Air Thermostat uses an outdoor temperature sensor to control the “Fresh Air” option built into the SmartZone-4X. Every SmartZone-4X has a built-in “Fresh Air Control” option that can be enabled…[Click to learn more about this feature]

The Outdoor Air Thermostat allows you to set HIGH and LOW outdoor temperatures. Above the HIGH or below the LOW fresh-air intake will not run. In other words, you can tell the SmartZone-4X that you do not want fresh air to run when it is too HOT and/or too COLD outside.

Also, the Outdoor Air Thermostat gives you the ability to “demand” fresh air temporarily (in 5 minute increments)… AND, disable (pause) the automatic fresh air from running using the Outdoor Air Thermostat.

PLUS NOW the Outdoor Air Thermostat can be used to enable the ECONOMIZER (Free Cooling) feature on the SmartZone-4X board. In the past, we have used an Enthalpy Sensor to enable or disable the ECONOMIZER feature of SmartZone-4X but the cost and reliability of these types of humidity and temperature sensors can be prohibitive. The Outdoor Air Thermostat can be and affordable and effective way to utilize ECONOMIZER mode on the SmartZone-4X.
