General Components GC0653 Digital Timer / Thermostat Controller for Bison Heaters
Overview: The General Components GC0653 is the dedicated digital controller for Bison-series diesel air heaters. It allows full control of heating output, temperature regulation, fan-only ventilation, and programmable on/off scheduling — giving you precise climate control for boats, RVs, cabins, or vehicles equipped with a Bison heater.
- Thermostat (Setpoint) Mode: Set ambient temperature between 5 °C and 35 °C; controller maintains heat automatically.
- Variable Heat Mode: Manual heat intensity control from low (P1) to high (P7) — ideal for custom comfort or rapid warm-up.
- Ventilation Mode (Fan Only): Run blower without heat for air circulation or cooling without fuel usage.
- Programmable Timer / Scheduler: Program up to three start times per day, for any combination of days — ideal for pre-heating before use or timed operation.
- Compact digital interface: LCD display with intuitive button / knob controls for easy setup and mode switching.
Why You’ll Like It: GC0653 gives you flexible, automated climate control with minimal effort — whether you want warm-up before wake-up, temperature hold while underway, or simple ventilation on mild days. It centralizes control and reduces manual thermostat/timer juggling.
Built for Marine & Mobile Use: Integrated in Bison’s diesel-fired heater kits for marine, RV, and off-grid applications. Provides reliable control even under vibration, variable voltage, and compact-space conditions. Works with Bison heaters from 2 kW up to higher-capacity models depending on installation.
