When using Flex Daily, what are my options to protect my pipes and heads from freezing damage, using the Iro 2 as my controller? Is this (below) an accurate summary?
- Rely on Iro’s capability to get ambient temperature information from weatherstations, hope that I can find a weather station near by, hope that the remote weather station has accurate and reliable ambient temp reporting, and hope that Iro 2’s non-adjustable fixed 32 degree threshold is sufficient. This option maintains an accurate Current Moisture Balance calculation for each zone. This option maintains ability to water a zone manually even if it’s freezing or below.
The remaining options do not (presently) maintain an accurate Current Moisture Balance calculation for each zone, nor do they allow for manually watering a single zone (my pool in my case).
Connect a hard wired freeze sensor to Iro 2 terminals ? and ?. What kind of hard wired freeze sensor is required?
Connect a remote freeze sensor to Iro 2 terminals ? and ?.
Use an external home automation system’s relay contacts, influence by the automation system’s specified temperature, to control open/close Iro 2’s common wire connection.
Thank you for the assistance.
