Getting 8e alarm
Ent water sensor., sensor is in well w paste.,
Changing sensors today .
Booty is my question,
Set point @ 45
2 compressors running @ 50%
My enter water temp drops to 43 as low as I have seen .
My other question is why are both compressors running., I am thinking
I only need one.,
I am sure the reasoning for the alarm is that both are running,
Now that being said., there is no soft load on the 695
controller
And the ent water temp stays around 43 to 45 ( set point )

Ah brain fart, could it be that only one compressor would
Run around 85% and the machine know this, so it runs both.,
Also I am thinking to just lower the ent water temp set point ,
Ah another fart. Is there where cw reset comes into play?
Btw changing machine in few months
Menu P 4 leave water temp set at 35
Diff to start 2*
Thx

Check to see if the configuration is set to equal loading or staged. Equal loading means one compressor then two compressors then load one compressor then load other compressor. Staged would be one comprssor fully loaded then start 2nd compressor.

increases the water temperature differential

Hows your oil temp?

I don't believe that sensor is in a well, I would double check that before you take a bath.

I have a couple of 99's that are only compression fittings.

Sensor is in a well we changed both.,

I like the idea about Equal or staged loading , not in this config though
Thx

Oil temps ok.,

The machine is running fine, thx everyone
However those little red clips that go on the 1U1 sometimes makes a bad connection

that would be a fun one to play with if it were possible. this chiller and all of the control versions following this one don't have that option. where are you getting this info?

[Pat A/C]

Usually this alarm is caused by the chilled pump off for which ever reason, and the chiller is still running and to protect itself it goes into this alarm

Is your chiller equipped with a water flow switch if it is then you should not be getting this alarm onless the flow switch is not working right

It could be the sensors that are defective i am surprised they are in a well usually they are in direct contact with the water

If they are in direct contact make sure you install it good and do not install it to in where it could touch a refrigerant tube and give you this alarm

I had this problem once I replaced the sensors checked the flow switch at the end my problem was the main display pannel. Entering water display just starting going out of wacky meaning temp flucting up and down like crazy
