Bright idea: The Primos 250 Controller
Bright idea: The Primos 250 Controller

The Prozeda Primos 600 solar thermal controller has 6 x temperature inputs ( PT 1000 sensor ), 4 x 230V outputs & 2 x additional low voltage outputs with Pulsed Width Modulation (PWM) to control high efficiency pumps. It also has a connection for Vortex Flow Sensor for yield measurement. This controller is predominantly for solar thermal applications with various hydraulic layouts including systems with two collector fields or two stores. It can also be used to control various back up energy sources and to operate diverting valves within the hydraulic circuit. For simpler solar applications with one collector field, the Primos 250 will suffice and still has the ability to data log and web view system information as standard, this control also can control HE pumps and has a relay output to control another heat source.

The Grandis 600 HK will perform the same duties as the Primos 600 & 250, however this controller is more advanced and has 10 x temperature inputs ( PT 1000 sensor ), 8 x 230V outputs & 2 x additional low voltage outputs with Pulsed Width Modulation (PWM) to control high efficiency pumps, it also has a connection for 2 x Vortex Flow Sensors for yield measurement. The Grandis 600 HK will also control and weather compensate two separate mixed heating circuits, this is ideal for high temperature panel heating systems working alongside mixed lower temperature under floor heating, both controllers are available to connect with a Building Management System (B.M.S ) and also sounds an audible alarm on any system error.
