Hi, thanks for a great product and backup service.
We have several OS units here. One in particular controls a master valve that opens the main pressured system to a large sub branch that then splits off to several controlled lines. The sub branch has pipe sections joined with couplings and rubber lip style seals and cannot be left pressurized due to leaks from this style of seal. Therefore I run a mastervalve adjustment of negative 330 seconds. Tiny issue is I cannot input a negative number via the mobile IOS app (2.4.86) firmware 2.2.1 rev2, I have to hold my finger on the button for a minute to get to -330.
Like the subject says, just polishing the little things.
