Raw Blame History

ThermIQ — Hardware Reference

Crypto Miners

Item	Spec
Model	Antminer S19J (x2)
Power supply	2x Schuko per miner
Power isolation	Individual LS breaker + contactor per miner
Contactors	K10 (Miner 1), K11 (Miner 2)
Feedback	Hilfskontakt per Schütz → RevPi DI
API	Braiins OS gRPC, port 50051 (`PerformanceService`)
Auth	Bearer token (`aWzKUJcmbyBMiTbo` — replace in production)
Network	Fixed IP, wired Ethernet only

Pumps

ID	Model	Supply	Control	Notes
P3	noname pump (miner cooling loop)	230 V AC	Relay on/off via RevPi DO	No speed control — simple contactor
P4	Wilo Stratos PICO plus Art.-No. 4244373	230 V AC	0–10 V via RevPi AIO AO1	Shielded cable
P5	Wilo Stratos PICO plus Art.-No. 4244373 (Glykol)	230 V AC	0–10 V via RevPi AIO AO2	Shielded cable; ⚠️ missing dotted line in Funktionsschema_Vorlage_Hydraulik.pdf

BMS Connect Module (Wilo Art.-Nr. 4257834): retrofit module for BMS integration.

0–10 V analog input for setpoint
SSM/SBM relay outputs (potential-free)
Digital input (configurable: extern AUS / MIN / MAX)
Max ambient: 60°C, SELV galvanically isolated

Valves

ID	Model	Actuator	Supply	Control
RV1	Belimo C320Q-J	CQ230A	230 V AC	Relay K3/K4 (AUF/ZU)
RV2	Belimo C320Q-J	CQ230A	230 V AC	Relay K5/K6 (AUF/ZU)

Note: If only one control input per valve is used, relay block can be reduced. Hand/0/Auto switches recommended for commissioning.

Dry Cooler (Rückkühler)

Item	Spec
Fan	230 V AC
Relay	K2 (24 V DC coil, switches 230 V)
Control	RevPi DIO DO_RK
Feedback	Optional fault signal → RevPi DI
Interlock	Enable only when oil and pumps OK

Heat Pump

Item	Spec
Model	Buderus WLW186i
EVU Input	I1 — dry contact ONLY
Relay	K7 (potential-free, 24 V DC coil)
Control	RevPi DIO DO_EVU_SPERRE
CRITICAL	Never inject voltage into EVU I1 — contact only

PLC: RevolutionPi

Module	Function
Core	CPU, Ethernet, Linux
DIO	Digital I/O (relays, contactors, safety feedback)
AIO	Analog I/O (0–10 V pump setpoints, sensors)

RevPi runs Linux, MQTT client, connects via LAN to industrial switch. If RevPi crashes → miners must shut down (hardware safety ensures this).

Inverters

Item	Spec
Model	Deye hybrid inverter(s)
Interface	RS485 Modbus (NOT Modbus TCP over LAN — unreliable)
Library	sunsynk for Raspberry Pi
Ref	YouTube: https://www.youtube.com/watch?v=u9df0YHfNtM

Energy Meters

RS485 Modbus
Connected via USB RS485 gateway on Raspberry Pi or RevPi

Network Hardware

Item	Spec
Switch	Industrial, wired Ethernet only
Site Server	Intel N100 Mini PC (e.g. Beelink EQ12) — Node-RED + Mosquitto + Home Assistant (Phase 1); DIN rail via adapter
RevPi	Fixed IP, MQTT client
NTP	Required for timestamps
WiFi	NOT used for any critical energy component

Power Distribution (Schaltschrank)

Component	Notes
Q0	FI/LS (RCD + circuit breaker) for whole cabinet
230 V AC bus	From Q0
24 V DC PSU	Fed from AC bus, supplies RevPi, relay coils, safety circuit
LS Miner 1/2	Individual breakers before K10/K11
LS Pumpen	Breaker for P3, P4, P5
LS Ventile	Breaker for RV1, RV2
LS RK	Breaker for Rückkühler fan

Storage Components

Pufferspeicher: buffer tank for thermal energy
Warmwasserspeicher: domestic hot water tank
Batteries: coupled to Deye inverter for energy storage
Smartmeter: grid metering

Sensors

Flow sensor (FLOW OK — NC contact to safety relay)
Temperature sensor (TEMP MAX — NC contact to safety relay)
Emergency stop buttons (E-Stop 1, E-Stop 2 — NC)
Reset button (NO)
