PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in product or

property damage.
If W2, W3, and E on any 3 stage heater (18, 20, 24, or

30kW) are individually connected as with outdoor

thermostats or any other situation, emergency heat relay must

be used. This relay is in kit Part No. KHOT0201SEC and is

normally used with kit Part No. KHAOT0301FST for 2

outdoor thermostat systems.

CAUTION

!

The controls are factory circuited for single--stage operation. For

2--stage operation, use outdoor thermostat kit Part No.
KHAOT0301FST, and for 3--stage use both kits Part No.

KHAOT0201SEC and KHAOT0301FST.
