power supply to the heater is switched on. The heater will only switch ‘ON’ (red
light indicator illuminated) when the following criteria are met ie:
• Water circulating pump is ‘On’ delivering in excess of the minimum flow
rate of water (see flow requirement information - page 16)
• Water temperature set point (required temperature) is set to a higher
value than that of the water (via the digital thermostat - refer to page 16)
If after initial power up either the Clear NO / LOW FLOW or Amber OVER TEMP. TRIP
neon indicators are illuminated please proceed to the troubleshooting section.
Select your required temperature (described earlier in this booklet). The
contactors will now click in and the cascade time delay function will begin. In
5-seconds time the first bank of elements will be switched on together with
the red HEATER ON neon indicator. Following a further 5-second time delay the
second bank of elements will be switched ‘ON’. Following a further 5-second
delay the third bank of elements will be switched ‘ON’. This sequence of staged
energisation (timed energisation) will continue depending on the power output
of your heater (see table).
N.B -
The number of banks your Titan Optima heater has depends on the power
output of the heater, please refer to the power requirement section earlier in
this manual to check the number of element banks within your heater.
