[tks 13]

Dear bro and sis,

Recently just bought a 2nd hand hailea HC 1000a.

Any guru knw how to set it as 2 degree then run(eg set 26 when reach 28 it start to run)?

Currently this one is 1degree run,pls help.

What is the best L/hr pump to use for it?

My chiller keep running n running and Derek(chiller repair guy) suggest tune it to higher flow.

I'm using 2000l/hr pump,is it sufficient?im tuning it to max already it seem abit better but it still run very often.pls advice.

Thank you all for the help in advance

To control 2 degree diff, u need a external thermostat to override the one on the chiller. U can try use 4000l/hr pump and see if it improve.
