Quality HVAC Controls
Thermostats, Non-Digital
Erie offers advanced design in electronic microprocessor based thermostats and controllers. Erie combines
the simplicity of a thermostat with the versatility and power of a controller. Ease of installation is combined with
the flexibility of applications and maximum compatibility. Proportional plus integral (PI) control algorithms with
advanced adaptive logic guides the microprocessor based units. This provides precise and stable control under
varying system capacity and load conditions, without the need for tuning or calibrating the control algorithm.
0-10 Vdc Controller Thermostats
The T167 thermostats provide proportional control of
cooling fan coil damper and fan system.
