Frequently Asked Questions
Which Hydro Touch model is right for my site?
ORP models (CHYT0454AU and CHYT0444AU) use inline sensors with no panel. FAC models (CHYT0434AU and CHYT0433AU) use sensors in a panel-mounted probe block. Single-pump models switch a salt chlorinator through the chlorine GPO and dose liquid acid, while twin-pump models dose both liquid chlorine and acid.
Can Hydro Touch control a salt chlorinator?
Yes. The single-pump models (CHYT0454AU and CHYT0434AU) include a chlorine GPO with timer to switch a salt chlorinator, and CHYT0454AU also includes a Gold ORP probe for salt chlorinators. Hydro Touch adapts to all electrolysers (plug model).
Is Hydro Touch compatible with multi-acid pH reducers?
Yes. Hydro Touch is 100% compatible with new chemical concentrations, including the new multi-acid pH(-).
What pool and spa volumes does Hydro Touch suit?
Hydro Touch suits pools and spas with volumes up to 160,000 litres. Different peristaltic pump flow rates are available to match the pool volume.
Can Hydro Touch be monitored remotely?
Yes. Remote monitoring with the Waterlink Modem is available as an upgrade, along with temperature measurement, a flow switch component, an FAC probe and a tank level and alarm relay.
What warranty applies to Hydro Touch?
Hydro Touch is backed by Waterlink’s standard commercial warranty. Full terms and coverage are available at waterlink.com/warranty.
