Best for |
| SZ7510T |
−50 to +99 °C |
1 SPDT relay, 8 A |
Water chillers, display coolers and cold rooms with on/off control; touch keypad |
| SZ7510-P |
−50 to +99 °C (7510 platform) |
1 SPDT relay, 8 A |
Same applications as the SZ7510T; a common like-for-like replacement |
| SZ7569P |
−45 to +99 °C |
1 relay, 20 A (compressor rated) |
Switching a small compressor directly; selectable cooling or heating, compressor time delay, sensor-fail auto mode |
All three use an NTC probe and run on 230 V AC. The 8 A relay of the 7510 series is normally used to drive a contactor or a small load; for a compressor switched directly by the controller, the 20 A SZ7569P is the safer choice. When replacing an old unit, match the model number on its label, or WhatsApp us a photo and we will confirm the replacement.

Sub Zero FAQs
Which Sub Zero controller is used for a water chiller?
Most water chillers and display coolers use the Sub Zero 7510 series (SZ7510T or SZ7510-P): on/off control from −50 to +99 °C with an NTC probe and an 8 A relay that switches the compressor contactor. If the controller must switch a small compressor directly, use the SZ7569P with its 20 A compressor-rated relay and built-in compressor time delay.
What is the difference between the SZ7510T and the SZ7569P?
The SZ7510T is an on/off chiller controller with a touch keypad and an 8 A SPDT relay. The SZ7569P has a 20 A compressor relay, selectable cooling or heating, a compressor short-cycle delay, settings memory through power cuts and automatic operation if the sensor fails.
Which sensor do Sub Zero controllers use?
Sub Zero chiller controllers use an NTC temperature probe (the 7510 series uses the SZ-N75 probe). Replace a damaged probe with the same NTC type; a PT100 or thermocouple will not read correctly.
What is the panel cut-out for the Sub Zero 7510 controller?
The 7510 series fits a 29 × 71 mm panel cut-out, the standard size for compact refrigeration controllers.
Is Voltkart an authorised Sub Zero distributor?
Yes. Voltkart is an authorised Sub Zero distributor and supplies genuine Sub Zero controllers with a GST invoice and delivery across India.
