Cover Mode; Boost Mode; Spa Mode - Davey DPLGEU Instalación E Instrucciones De Funcionamiento

9.1 COVER MODE

A pool's exposure to UV contributes significantly to the pool's total chlorine demand (ie. the amount of
chlorine the pool uses). Excessive amounts of chlorine in a pool with a cover on, can significantly shorten
the life expectancy of the pool cover, if left for long periods of time (eg. weeks). Turning on the COVER
MODE reduces the chlorinator cell duty cycle by 80% of its current setting. COVER MODE can only be
selected from the menu if the ORP probe not connected.
For example:
• If the EcoSalt2 is on for 8 hours per day, the CHLORINE OUTPUT is set to 50%, but the COVER
MODE is on: the EcoSalt2 cell duty cycle is only 48 minutes, of that day;
• If the EcoSalt2 is on for 8 hours per day, the CHLORINE OUTPUT is set to 25%, but the COVER
MODE is on: the EcoSalt2 cell duty cycle is only 24 minutes, of that day.
COVER MODE can also be triggered remotely by an automated pool cover controller. By closing the
terminal block contacts on the rear of the EcoSalt2 power supply (ref figure 9.2), Davey Lifeguard will
remotely switch to COVER MODE. This can be overridden by user intervention, by following the steps
explained previously.

9.2 BOOST MODE

Should the pool experience a heavy bather load, debris/contamination, or extreme warm weather, there
may be a need to super-chlorinate the pool. Turning on the BOOST MODE increases the chlorinator cell
duty cycle to 100% and overrides the cell current (output) to 100% for a period of 24 hours.
9.3 SPA MODE (for use if NO ORP probe is connected)
The Davey Lifeguard is compatible with large swimming pool applications as well as much smaller spa
applications. Turning on the SPA MODE reduces the chlorinator cell duty cycle by 80% of its current setting.
For example:
• If the EcoSalt2 is on for 10 hours per day, the CHLORINE OUTPUT is set to 50%, but the SPA MODE
is on: the EcoSalt2 cell duty cycle is only 1 hour, of that day;
• If the EcoSalt2 is on for 10 hours per day, the CHLORINE OUTPUT is set to 25%, but the SPA MODE
is on: the EcoSalt2 cell duty cycle is only 30 minutes, of that day.
SPA MODE can only be selected from the menu if ORP probe is not connected.
