I'll check the voltage again.
as far as i know you have a single controller and not multiples, why do you need an ice cube? the PSR should should stand alone shouldn't it?

the ice cube should be installed as an isolation between multiple controllers if i am not mistaken.

Isn't a big contactor with a 7.5 HP rating likely to have a coil that draws too much current for a master valve output?

a psr simply closes the circuit, if you have 24vac output you should be golden

PSR coils routinely outdraw irrigation controllers today - they aren't designed for weenie controller circuits that have 20VA supply transformers.

The other possibility is that you have bad contacts in the ice cube causing the relay to "chatter" when the controller is energizing the ice cube, which would cause the pump to draw more, or, the coil on the relay is drawing more since it is constantly pulling in and releasing....

Just a thought...

i don't understand the use of the cube

below is a copy of the hunter psr specs

Pump Start Relay Model Chart
MODELS DESCRIPTION
PRS-22 Double pole/single throw pump start relay for 120 VAC pumps up to 2HP or 240VAC pumps up to 5HP

PRS-52 Double pole/single throw pump start relay for 120 VAC pumps up to 5HP or 240VAC pumps up to 7.5HP

PRS-53 Double pole/single throw pump start relay for 120 VAC pumps up to 5HP, 240VAC pumps up to 7.5HP, or 240VAC pumps up to 10HP (three phase)
PSRB Used to boost controller output power available to operate larger pump start relays if necessary

we're not getting all the info morris, i'll be back in a few days

I think the TECO relay was already in place (or maybe not) - but you aren't including the VA requirement of the relay coils, and that is key - no way the old Hunter SRC controller could feed any 24VAC relay it might encounter.

Sure be nice if one of you "pros" would explain why an "ice cube" was used in a single clock situation. Pump start relays can be wired any which way (115/240), so I don't understand this whole deal, but, it is Florida.

Could be that the controller controls the ice cube with 24 vac and the ice cube controls the pump start with 110 vac, if the PSR coil is a 110 coil.
Most of the larger PSR's I deal with use 110 coils.
