Laars Endurance help

Hi. How are you guys. I have a Laars Endurance EBP175. I would like to know if I can change out the unti condensing valve to a zone valve. Thanking you.

Exactly what is a unti condensing valve?

Anti-Condensing Valve

Part numbers:
Complete unit: 2400-538
Actuator only: 2400-539
Cartridge only: 2400-141

I can see why you ask, as the Laars provided parts are very expensive.

If you only need the actuator
It is the same as this and saves you $150.00

But as you can see does not have the end connector which you can re-use from your existing.

Or if it's just the cartridge in the valve you need to change,

It has to be between one of these two and it's cheaper than installing a new valve.




Edit: being reminded of the importance of being provided serial numbers different year models can use this model

Part #: 2400-451
Laars will have different color wires and connector for the two leads.


To answer your question, yes you can use a zone valve (which is what it is).
The original is high Cv. Your common honeywell zone valve has a Cv of 3.5. So you should opt for a customizable pop top actuator and valve body with higher Cv. I cannot answer whether that is purposeful design and is absolutely needed.
Or find a good deal, such as https://www.ebay.com/itm/194866339617
