Energy Savings & Comfort

One Control, All the Benefi ts ENERGY SAVING FEATURES

Zone SynchronizationEvery tekmarNet® Thermostat communicates to agree on a common, or ‘synchronized’, start time. The result is a boiler that runs more efficiently and cycles less.

Zone Post PurgeAt the end of a cycle, the zones are held on while the boiler is off. This moves residual heat out of the boiler and into the zones where it belongs.

Automatic Boiler DifferentialAutomatically adjusting the boiler differential to changing conditions ensures longer running times and reduced boiler short cycling.

CONVENIENT FUNCTIONALITY

Simple ProgrammingPre-programmed to suit most applications, setting up a House Control System is almost too easy. And with Access level adjustment, the control will stay as you left it.

$aving IndicatorA ‘$aving’ icon displays on screen when the House Control is using any of its many energy saving features.

MonitoringThe House Control monitors everything from pump run times to outdoor temperature extremes to boiler usage, then organizes it in a simple menu for access at any time.

Outdoor Reset with Indoor FeedbackTraditional outdoor reset saves energy by adjusting the supply water temperature to match changing outdoor conditions. This allows the system to operate at a reduced temperature for much of the year, anticipating interior load changes before they occur.

tekmarNet® House Controls take outdoor reset one step further with ‘Indoor Feedback’. tekmarNet® Thermostats communicate with the House Control, allowing it to fi ne-tune supply water temperatures based on actual interior heat gains or losses. The end result? An integrated HVAC system providing unmatched occupant comfort and unparalleled system effi ciency. Remarkably, Indoor Feedback is just one of the House Control’s many exciting features.

With tN2 Thermostats you can use existing 2 conductor, 18 AWG wire to replace old thermostats with models that offer the energy savings, comfort and convenience your customers want.
