Thresholds
Set limit values at three levels — company, building and pool — which override each other.
Thresholds determine the allowed range of each parameter. AquaTrace uses them to automatically check measurements and show warnings for out-of-range values. You manage them via Thresholds in the admin menu.
Three levels that override each other
Thresholds work in a cascade of three levels. AquaTrace always uses the most specific value available:
- Company — the default values for your entire organization.
- Building — overrides the company values for one building.
- Pool — overrides everything for one specific pool.
This lets you set a general default once and only deviate where needed. Every screen clearly shows which value is inherited and which is set specifically.
Company level
On the Company tab you set the default values that apply to all buildings and pools, unless overridden elsewhere.
Building level
On the Building tab you choose a building and apply different values. Anything you don't change here keeps following the company value.
Pool level
On the Pool tab you set values for one specific pool — handy for, say, a paddling pool with different requirements than a competition pool.
Setting a threshold
Click Add threshold to open the form. A threshold can be a range (a minimum and maximum), a picklist of allowed values, or a calculated value — such as combined chlorine, which AquaTrace derives from free and total chlorine.
Legal limits (VLAREM)
After saving a new bath type, AquaTrace offers to set the thresholds of that pool to the legal limits: choose Apply limits or Not now. On the Pool tab, the Apply VLAREM limits button does the same.
If the pool already has its own thresholds for some of those parameters, a second step names them and asks you to confirm with Replace. Only those values are replaced. Parameters that are not part of the preset, because the law sets no limit for them, are left untouched and nothing is deleted.
An effective threshold that is looser than the law gets the label Deviates from VLAREM: a wider warning band or a missing critical bound. For an enabled parameter that the law limits but that has no threshold, you see No threshold for: …. A value exactly equal to the legal limit is compliant.
The humidity limit only applies to an indoor bath. If the bath is outdoors, such as a hot whirlpool or a plunge pool, switch off the humidity parameter for that pool.
Applying only changes the parameters in the list. If the pool has a threshold for a parameter that has no legal limit for this bath type, such as humidity for an outdoor pool or chlorine for a natural pool, that threshold keeps applying. The dialog names those parameters; switch them off or delete the pool's own threshold if you do not measure them.
