This thermostat has been designed to operate with any installation which has a
RESISTIVE load not exceeding 2500 W @ 240 VAC or 1250 W @ 120 VAC such
as electric baseboards, radiant ceilings and floors, electric convectors, etc. It is
not compatible with a low voltage controller used by a central heating system or
systems using a contactor or a relay whose current is under 1.0 A.
Electricians or experienced technicians should install the thermostat.
This thermostat is designed to be used with a self-protected heating system
equipped with thermal cut off and circuit breaker.
