Do not exceed 16 amp resistive load rating or 1 Hp @240V. Check that load is rated for 240V. Check that line is 240V from double-pole circuit breaker. Test that 240V circuit is carrying at least 80% rated value or at least 192Volt. Flip circuit breaker fully off and then fully back on. Always reset timer before programming.
