incorporated in the installation are in a mode to ensure that the air
curtain can operate.
By switching each rocker switch to the down position the
following combinations of control can be achieved:
• ON 1 & HEAT SET 1 provides low air flow and low heat.
• ON 1 & HEAT SET 2 provides low air flow and high heat.
• ON 2 & HEAT SET 1 provides high air flow and low heat.
• ON 2 & HEAT SET 2 provides high air flow and high heat.
• ON 1 provides low ambient air flow.
• ON 2 provides high ambient air flow.
