Many heating and cooling systems consist of equipment and controls, which are installed as stand alone pieces only able to operate their part of the system. Without integration of this equipment, conflicting demands often compromise efficiency, comfort, and equipment reliability. Ironically, these are the benefits owners demand the most.
tekmar offers affordable heating & cooling controls designed specifically to integrate the different equipment to get the best performance from your system.
To have a coordinated operation of all the equipment, a system control is required to make the smart decisions based on information gathered from all system components. To gather this information, we have developed tekmarNet®, a communication link built directly into our Performance & Designer series controls. This link allows thermostats and other controls, located throughout the building, to coordinate their operation and maximize the efficiency of the overall system.
Our tekmarNet® product line offers flexible solutions to improve system operation; below are some examples of how this is achieved.
Each zone equipped with a tekmarNet® thermostat provides information back to the system control. This Indoor Temperature Feedback allows the Outdoor Temperature Reset logic to consider the internal heat gains and losses of each zone to continuously fine-tune the water temperature delivered to the heating system. Occupant comfort is greatly improved by maintaining steady air temperatures in the zones while heating plant efficiency is increased by operating the boiler and mixing systems at their lowest possible temperatures.
Outdoor Temperature Reset with Indoor Temperature Feedback improves the quality of today’s high efficiency boiler to ensure the boiler operates at the lowest possible temperature for the longest required cycle, maximizing performance.
tekmarNet® allows the on-times of all zones within the building to be coordinated through continuous communication. This Zone Synchronization prevents potential short cycling of the equipment by preventing small load zones from calling for heat independently.
tekmarNet® allows for the system control to know when the last zone calling for heat is turning off. Before closing the heating zone valve, the control turns off the boiler, however it maintains the pump running to purge the residual heat within the boiler into the heating zone. Zone Post Purge increases efficiency by reducing boiler standby losses.
tekmarNet® communication between thermostats allow for the creation of cooling groups. A Cooling Group is a selection of heating thermostats that communicate with a single cooling thermostat for an air-handling unit. The cooling thermostat will interrupt any heat demand during a cooling operation, and for a specified lockout period afterwards, thereby preventing simultaneous heating and cooling operations.
