Control Options for Model TSD IG

Indirect Gas Heated Options

* Recommended

*Door Switch/Magnetic -- A non-mechanical door switch that turns the air curtain on when the door is

opened.

* Hand/Off/Auto Selector Switch (Panel Mounted) -- Switches between the unit running constantly in
the hand position, off, and auto, which only runs when the door switch is activated.

*Heat On/Off Selector Switch (Panel Mounted) -- Turns the heat on and off while the fans are running,
or when used in conjunction with a thermostat can disable the heat.

*Thermostat (Panel Mounted) -- Turns the gas heat in the unit on and off while the fans are running
based on the room temperature.

Other Options

Cruise Control Programmable Switch -- Digital logic controller with an LCD display that takes the place

of several individual control components including a Built-in Time Delay Relay, On/Off/Auto Switch, and
Heat On/Off Switch.

Disconnect-Fused -- A switch that will disconnect all power from the unit so that the unit can be serviced
or inspected and includes fuses for circuit protection.

Disconnect-Non Fused -- A switch that will disconnect all power from the unit so that the unit can be
serviced or inspected.

Door Switch/Roller-Plunger -- A mechanical door switch that turns the air curtain on when the door is
opened.

1/2 hour increments, specify up to 4 time periods per day).
