The SEProX is RESOL DeltaSol BX controller OEM Version. It is equipped with 4 relay outputs as well as 2 PWM outputs for the speed control of energy-saving high-efficiency pumps; one of the PWM outputs can be  converted into a 0-10 V signal output. Additionally, the controller comes with 5 Pt1000 sensor inputs, two analog Grundfos sensor inputs ( Except GEN-5 VFS/RPS version), an impulse input as well as a supplemental fused output (L' ) for the connection of an actuator. The integrated SD memory card slot enables an easy datalogging to an SD memory card as well as a quick and effortless transfer of logged system data to a PC. The extra-large display enables a precise visualization of the system status. Pre-defined functions allow easier setup of the system; functional additions such as a drainback function extend the range of applications. The SEProX has a RESOL VBus® and works with all RESOL VBus devices: KM2, DL2, DL2PLUS or DL3 e.t.c.

Resol DeltaSol MX controller is a free-programmable controller with 15 inputs and 14 relay outputs; MX gives you flexibility to combine solar thermal and hydronic heating functions to control your solar and/or hydronic systems. For example, "Function Block" logic of the MX allows you to apply two temperature settings, one temperature differential and 4 reference relay logics: OR, AND, NOR and NAND to control a relay output. A MX controller includes all possible logics for a solar thermal system and popular hydronic heating/cooling control logics, heating/cooling mode switch over automatically,  as well as energy saving logic when solar heating and hydronic heating work together. 

It is an all-in-one human interface controller for solar thermal, hydronic heating, hydronic cooling control, and can be applied to convential heat sources and heat pump systems.
