To manage sliding temperature it is necessary to purchase the external probe accessory code 013018X0
If a hot water tank probe (not supplied) is used, it is necessary to purchase the NTC probe accessory code
1KWMA11W (2 mt.) or code 043005X0 (5 mt.)
If a hot water tank thermostat (not supplied) is used, it is necessary to purchase the kit accessory code
013017X0 (to be connected in place of the Hot Water Tank Probe)
If a cascade probe (not supplied) is used, it is necessary to purchase the NTC probe accessory code
1KWMA11W (2 mt.) or code 043005X0 (5 mt.)
