The F29 houses 2 relays. Relay 1 has S.P.D.T contacts. Relay 2 has S.P.S.T
normally open contacts. Relay 1 is normally regarded as the pump control
relay and relay 2 is normally regarded as the alarm relay.
With the HD terminal linked to the NO terminal of Relay 1, the F29 can
directly control a single phase motor up to 2.4kW via its NO contacts.
Without the HD terminal link in place, relays 1 & 2 are limited to directly
controlling a motor to 0.75kW.
Both relays can control motors of any
required size via interposing contactors.

IMPORTANT:
When directly controlling a pump motor through relay 1, always
link the HD terminal to relay 1 Normally Open terminal and make sure the
maximum switched motor current never exceeds 10 Amps. On a pump motor
P1 must not exceed 2.4kW.
