Thermostats, measuring instruments & calorimeters
Universal calorimeter module for solar and heating systems. Graphic display for indication of flow and return temperature, heat quantity, output, flow rate and sensor faults (balance values are also stored in the case of a power failure). Suited for solar systems with propylene-glycol-mixtures of 0 ... 70 Vol %.
The WMZ-G1 is a measurement and display unit for solar thermal systems and conventional heating systems. It is possible to connect up to two Grundfos Direct Sensors™, which measure the temperature as well as one additional value - depending on the type: flow rate, relative or differential pressure. If at least one of the sensors measures the flow rate, the heat quantity can be calculated. the WMZ-G1 also monitors the operating status of the system and displays deviations.
- Recording of:
Flow temperature, Return temperature, Power, Heat quantity, Flow rate,
Pressure, Differential pressure, System errors
- Easy connection
- Dot matrix display
- Function control
- Configurable control parameters
The RESOL thermostat compares the temperature measured by a sensor with the preadjusted switch-on temperature. If this temperature is underrun (heating operation) the relay switches on. If the temperature is exceeded, the relay switches off. Depending on the adjustment of the switch-on and switch-off temperature, the controller operates in heating or cooling operation. Depending on the application area, all Pt1000-temperature sensors from our product range can be used. Electronic temperature controller (thermostat) with combined LC-display for indication of the actual temperature and adjustment parameters (menu-driven). One temperature sensor from our product range is required (Pt1000, e.g. FKP 6, please order separately).
Variable controller for circulation systems EC1
Variable controller for circulation systems
The purpose of a circulation system is to provide the consumer with hot water as quick as possible when opening the tap. The pipe line system for the supply of domestic water is simultaneously used as a circulation system so that by means of the circulation pump, water is passed through the water pipes even without having to open the tap. Via a flow switch in the cold water pipe, the unit monitors the water draw off. After opening the tap for a short moment, the circulation pump is switched on and will be switched off again due to the adjusted runtime. The tap operates like a “remote control“. This circulation pump control function is an eco-friendly and energy-saving solution in line with demand.
- Energy savings by economic pump control
- Tap station as remote control
- Hot water without delay
- Easy to integrate into existing systems
The RESOL V40 is a measuring instrument with a contactor for detecting the flow of water or water-glycol-mixtures and is used with the RESOL calorimeter. It is ready for use in the RESOL calorimeters. After a specific volume has passed, the V40 reed switch sends an impulse to the calorimeter. The heat quantity used is calculated by these impulses, the temperature difference and pre-defined parameters (glycol type, concentration, heat capacity etc.). Delivery includes connecting screw.
Version 1 is suitable for horizontal as well as for vertical mounting.
Version 2 is for horizontal mounting only.
The flow switch FS07 / FS08 is used for flow detection and incorporates a reed-contact, which will be closed as soon as the flow rate is larger than 1 litre/min.
Suitable for vertical installation only. Please pay attention to the flow direction indicated on the housing!
Mini digital thermometer
