Manual Controls

A. On/Off Switch

The On/Off Switch supplies power to all replace functions.

When the switch is in the “ -- ” position, the unit is on.
When in the “ O ” position, the replace is off.

B. 3-Position Selection Switch

The 3-Position Selection Switch changes the mode

the replace operates in and has three (3) positions: “

MANUAL ”; “ OFF ”; and “ REMOTE ”.

When in “ REMOTE ” mode, the replace's three levels of

operation are controlled by the ON and OFF buttons of the

remote control.

In “ OFF ” mode, power to all functions is cut off.

In “ MANUAL ” mode, the replace's three levels of

operation are controlled by the Manual Control Buttons.

C. Manual Control Buttons

The Manual Control Buttons operate the replace levels
sequentially (from off): ames only; to ames and low heat;
to ames and high heat.

The level is increased every time the “ -- ” button is

pressed, and the replace can be turned off at any point by

pressing the “ O ” button.

Resetting the Temperature Cutoff Switch

Should the heater overheat, an automatic cut out will turn

the replace off and it will not come back on without being
reset. It can be reset by switching the On/Off Switch to Off
and waiting ve (5) minutes before switching the unit back

on.

CAUTION: If you need to continuously reset the heater,

disconnect power and call Dimplex customer service at
