Circulation pump and UFH query

eugenedoc1

Hi,
Recently installed UFH upstairs and down and am trying to get used to working the system.
I noticed that when i set the stats at say 11deg and room temp was say 20deg i found the circulation pumps seemed to be still pumping.
Is this normal? should the system not shut down until the temp drops to 11deg.
Is there not a risk of the circ pumps burning out if they are on all the time.
Thanks

Know < nought about UFH but do know that stats are often wired wrong, as are timers by individuals who either assume they are all the same or cant read the instructions.

Most stats switch the power from one terminal to another in the stat so if the wrong terminal is wired the stat will be off when u expect it on and visa versa:)

Is that one pump serving seperate zones upstairs? Mine is wired so when a stat calls for heat, pump comes on.

Yeah seperate circ pump upstairs also.
I spoke with the plumber who said like i thought that the pump should only come on when the stats call for the heat. The electrician must have wired it to be on constant
