SR501 Solar Controller for Non Pressurized Solar Water Heater Controlling System
Main Technical data:
1 Dimension: 210 mm x 145mm x 40mm pressurized valve and un-pressurized valve are available for
selection
Main Functions: 1, Time display
Terminal layout of controller for electrical heater of 1500W • FU1: the fuse of controller, AC250V/2A L: live wire, N: zero wire, protective ground wire, please connect the ground reliably.
Max. Current: 10A ( @AC230V, for 1500W electrical heater, @110VAC,
for 750W electrical heater) wire connection is not positive and negative difference. - R2: designed for the electric tracing belt, electromagnetic relay, maximum current is 2A.
• Input ports
- T1: for NTC10K, B=3950, ≤135oC temperature sensor (PVC cable ≤105oC), designed for DHW circulation TCYC or AH function (optional).
designed for pipe anti-freezing function (optional).
T1, T2 temperature sensors are not included in the standard parts of delivery, which should be purchased separately.
Terminal layout of controller for electrical heater of 3000W • Power input N, L: 20A, for power connection, L: live wire, N: zero wire, protective ground wire, please use 2mm² cable to connect the ground reliably.
• Output ports
• Input ports
Note:
Warning With Auxiliary electrical heating, the user must install the leakage protector.
Advice regarding the installation of temperature sensors must not be laid close to 230 Volt or 400 Volt cables (minimum separation of 100mm).
when cable’s length is up to 50m, and then 0.75mm2 cable should be used. When cable’s length is up to 100m, and then 1.5mm2 cables should be used.
Installation of solenoid valve Flushing pipe and cleaning pipe before mounting the solenoid
valve. please select the solenoid valve which pressure is matched to the hydraulic pressure got from water tower.
is same to the voltage of power output of controller, check whether the filter of solenoid valve is completed, whether the body of valve has no damage. And during installation please pay attention to the water flow and return of solenoid valve, side with filter is the water input, water flow direction and arrow signal on the body of solenoid valve should be aligned in same direction.
or at the area where no more connected loss happened. To keep a long lifetime of solenoid valve, please pay attention toanti-frost, sun protection, and prevent broken damage from freezing or aging of body of solenoid valve.
It is prohibited to use a wrench worked on the coil wire and plastic parts, to ensure no damaged during installation and no torsion effect positioned on the solenoid valve, it is not allowed to install valve compulsively when tow connectors are not aligned.
please select cable of 1.0mm2.
water inlet pipe connected to the solenoid valve should be a kind of soft pipe or pipe is easily dismounted.
Note: one-way check valve integrated into the solenoid valve, so no one-way valve needs to be installed.
Installation This controller can only be installed in the place having an
adequate level of protection.
