Hi,
my CH and HW (tank) are controlled by a Smartfit T8617A 24h controller with Smartfit "S" system.
I would like to upgrade the main controller to have 7day (or 5/2) option and also the possibility to set different temperature for different time of the day. While 7 day controller are easy to find, ones which can set several temperature are not so.
From Honeywell the CM907 can do the above but cannot control the HW tank. The ST9400C is dual channel but will not let me select different temperature settings.
I'm looking for any options from Honeywell or other suppliers but would like to replace only display/control unit rather than the full system. Any suggestion?
