This feature is available, but in beta.
Introduction
Heat and frost protection uses Sensor-Driven Automation with an air temperature sensor. The Verdi Block Controller or Verdi Micro-Block Controller opens its valve when the air temperature crosses the Target you set.
Important note
Heat and frost protection is currently wired and on-device only. A temperature sensor protects only the zone whose controller it is wired into.
Before You Start
Each zone you want to protect needs its own temperature sensor wired into that zone's controller. One sensor cannot open valves on other controllers or start a protection sequence across several zones.
Automation will not turn on a pump controlled by another controller, including a parent pump controller linked to the zone (see Pump Control). Make sure the zone has water pressure when its valve opens.
Position each temperature sensor so it represents conditions in the zone it protects.
How to Set Up
Wire an air temperature sensor into the controller for the zone you want to protect.
Follow the steps in Sensor-Driven Automation, selecting the temperature sensor in the Sensor dropdown and setting a temperature Target.
Set Irrigate Below Threshold for the type of protection:
Frost protection: enable (green). The valve opens when the temperature drops below the Target.
Heat protection: disable (grey). The valve opens when the temperature rises above the Target.
Click Save, then repeat on every controller that needs protection.
Wireless Heat and Frost Protection (Roadmap)
Using one temperature sensor to start a protection sequence across several zones and a pump requires wireless sensor-driven automation. This is on the Verdi roadmap but does not have a release date yet. See Sensor-Driven Automation for details.
