Can Selec Temperature Controllers be used for both heating and cooling applications?
Yes, Selec Temperature Controllers can be used for both heating and cooling applications. These controllers are designed with dual control modes that automatically switch between heating and cooling based on your set temperature range. When the process temperature drops below the setpoint, the controller activates the heater output. When it rises above the setpoint, the same device triggers the cooling output. This makes Selec controllers highly flexible for temperature-sensitive processes where both actions are required, such as ovens, chillers, incubators, or packaging machines.
Most Selec Temperature Controllers, like the TC303 or TC513AX, support both ON/OFF and PID control modes, giving you precise temperature management. In ON/OFF mode, the output turns on or off completely based on the temperature deviation, which works well for simple systems. In PID mode, the controller adjusts the output proportionally to maintain steady temperature without overshoot. You can easily configure the controller through its front panel to assign one output for heating and another for cooling. This dual-function capability saves space, wiring, and cost compared to using two separate controllers.
If you connect the controller correctly—with relay or SSR outputs assigned for each action—it will automatically manage both functions without manual intervention. Selec also supports various input sensors like RTD (PT100) and thermocouples (J, K, T types), ensuring compatibility across applications. Whether it’s maintaining the temperature of a furnace or a refrigeration unit, Selec Temperature Controllers handle both with accuracy and reliability.
