Sehr got, thgoebel. Thank you very much.

Thats all for now.

I love this forum.

Thanks,

The Aseko unit:

Power supply 230 V / 50 Hz

Power consumption 14 VA

Fuse T80 mA

Over-voltage category II

Ingress protection IP5

By the way, can Shelly EM do the same as Shelly PRO 1PM?

Thanks again, thgoebel.

My configuration appears to be:
A. 1 Shelly 3EM - with contactor in front of 3-phase circulation pump
B. 1 Shelly PRO 1PM in front of 1-phase heat pump
C. 1 Aseko net chlorine/ph automatic - 1-phase (must be switched off when the circulation pump is switched off.) What is needed to achieve this?
D. If simple, connect a Shelly DS18B20 temp. sensor to the Shelly PRO 1PM or do I need a 2PM?

Thanks again, thgoebel.

I hand this over to my electrician. My cirkulation pump use 0,45 kw (not variable) and here in Norway we have 230 v system. I think a 3-fase give 410 v.

Danke sehr, thgoebel

Unfortunately, the Shelly pro 4PM is NOT a 3-phase device! To measure the power consumption of your 3-phase pump, a Shelly 3EM and a separate contactor will be needed!

To control and measure the (1-phase) heat pump, a Shelly pro 1PM may be sufficient.

A separate contactor needed, can you propose which one I should buy?

Old pool with 3-fase cirkulation pump and 1-fase heat pump (without wifi). Wish to control both and through wifi/lan. Need to stop the cirkulation pump every 12 hours and depending on water temp shut down the heat pump now and then. Shelly Pro 4PM and Shelly Pro 1PM seems to met my wishes incl. power consuming, acc. power and shedule everything.

Will history and set time be kept when power is cut off?

Can I use Shelly DS18B20 Temp. sensor in the same Shelly Pro 1PM as the heat pump?

Has Shelly another unit for 3-fase with wifi and history?
