Safety and alarms

Safety thermostat cut-out (SATK2210.)
Error code 69

HIUs configured to support low temperature heating continuously 
monitor the safety thermostat controlling the flow temperature.
If the safety thermostat is activated during a general cycle, the heating 
circulation pump immediately comes to a stop and the modulating 
valve is completely closed. 
After the user has removed the block imposed by the safety 
thermostat, operation can only be re-enabled when the modulating 
valves are completely closed again.
This means that if a domestic water cycle is in progress, the activation 
of the shut-off valve will be postponed until the end of that domestic 
water cycle.
