About this app

The tekmarNet® Internet Gateway app allows remote access to a tekmarNet® HVAC system. Users can view and change settings for each thermostat, including: temperature, heat/cool/auto, fan operation, relative humidity, schedules, and the away scene. In addition, the boiler system temperatures, firing rate, run times, and pump status can be viewed. All system data can be graphed on a chart. Users are informed of errors and warnings through email or text notifications. The 486 includes three alert inputs that can be used to monitor auxiliary equipment.

This looks like something an intern did in a week. For the high price of the 486, this should be much more polished. The UI should be slick and not clunky. As others have said, it should display changes to temperature and state as they happen and not require manual refreshes. There should be useful innovations like the ability to group thermostats and control the group instead of adjusring each thermostat individually. A company as large as Watts should be embarrassed to put their name on this.

You can set temperature with this app. That's all. You cannot schedule anything on the app. Also, after you change the temp you don't see if the unit is on or off it is not refreshing automatically, you need to close and reopen the app to get current status.

Thank you for your feedback! The schedule is available on the App, but it depends if the thermostat has scheduling capabilities. Please contact us at tekmar.customerservice@wattswater.com or at 1-800-438-3903 so we can look into this for you!

This is the companion app for Tekmar's new gateway model 486. This gives you similar app control as with the so-called "smart" thermostats of other companies, but with the superior Tekmar control system. I am using this and the gateway 486 with a hybrid radiant floor + forced air system (incl. radiant floor cooling) controlled by a Tekmar 406 and multiple model 557 thermostats. It works great and has all the app control features I would want.
