When the correct required temperature is displayed, press and release the P
button. The unit will then revert to displaying the current water temperature,
but will now control the water temperature, to a maximum of the required
temperature.
Time switching delay:
To prevent overheating of the components within the heater caused by
frequent ’On’ and ’Off’ switching (cycling) the digital thermostat has been pre-
programmed with a time delay function. This prevents rapid fluctuations in
water temperature from switching the heater ’On’ and ’Off’ more than once in a
two minute period. The time delay mode is indicated by the flashing of the Red
indicator (5) on the digital thermostat (see Fig.5)
Differential:
When the water has reached the required temperature the heater will switch off
and will not switch back on until the water temperature has dropped by 0.6˚C.
This value is known as the differential and is in place to prevent overheating to
the switch components caused by cycling.
Water Quality
The water quality
MUST
be within the following limits:
PH 6.8 - 8.0
TA (Total alkalinity) 80—140ppm (parts per million)
Chloride Content MAX: 150 mg/litre
Free Chlorine: 2.0 mg/litre
Total Bromine: Max 4.5 mg/litre
TDS (Total Dissolved Solids) / Calcium hardness 200— 1,000ppm
Titan Optima heaters are suitable for use with salt water pools with a salt
concentration up to 8000ppm (8g/litre)
For salt water pools with a greater salt content (such as sea water pools) the
Titan Optima Plus heater is required.
Water chemistry is complicated if in doubt seek expert advise.
Operating Your Heater
Upon completion of the installation, the water-circulating pump should be
run to purge the system and the heater of air (i.e. remove any trapped air in
the system and heater). On initial power up of the heater the clear POWER
neon indicator should illuminate and will remain illuminated as long as the
