Command Center Spa Side Controls

Tecmark Command Center Spa Side Controls are complete spa-side control packages designed for durability and user convenience in both new installations and replacement applications. They are available with two, three and four transmitter button configurations, and are equipped with a remote sensing thermostat, power cord, equipment status indicating lights and optional digital temperature readout. The Tecmark Command Center is integral in hot tub control and spa control.


The Command Centers utilize an electronic thermostat designed, developed and manufactured by Tecmark in our Mentor, Ohio facility. These units feature a thermistor/bulb assembly for remote temperature sensing. All thermostats are calibrated to open on temperature rise at the UL/CSA maximum allowable set point
with the shaft at the high stop position and are intended for pilot duty control of heater contactors. Standard thermistor cable length is 60 (1.5m) with a 5/16 (8mm) OD bulb for thermowell installation.


Tecmark Command Center technology incorporates a unique, tactile thermostat adjustment knob with each notch equal to approximately 1° F (.56°C) temperature The Command Centers feature high volume, miniature air transmitters for operation single function or four function switching controls. The faceplate design allows serviceability of individual transmitters without having to replace the entire unit. design conserves space and it is easily retrofittable to existing applications.


Typical Applications

The Command Center is primarily used at the spa-side to regulate the water temperature, and to control, via the air transmitter buttons, a variety of electrical devices including motors, lights, pumps, air blowers, and other associated equipment.
